This paper describes design techniques for bipolar and bicmos analog circuits. Comparison on such performances as transconductance, speed, matching, noise of bipolar and CMOS transistors are reviewed and compared. Design achievements such as a single core 12 Bit 1.5GS/s Analog to Digital Converter (ADC) [1] and a single core 12 Bit 3GS/s Digital to Analog Converters (DAC) [2] based on a fully bipolar 200GHz SiGeC technology are introduced to illustrate the advantages and drawbacks of a fully bipolartechnology for high speed data converters. A Quad 10 Bit 5GS/s ADC based on 4 interleaved ADC Core designed with a 120 GHz 0.18um bicmostechnology is also presented, to illustrate the advantages brought by the combination of bipolar and CMOS technologies.

An active ESD supply clamp for mixed voltage RF applications developed in advanced SiGe bicmos process is introduced. The clamp is designed using a three-stage architecture consisting of transient-detection, timing and beta-multiplication. The proposed design ensures the clamp has very low leakage even when circuits operate at supply voltages that are equal to or beyond the breakdown voltage of the core SiGe bipolar devices. The clamp's turn-on characteristics spans the full duration of the actual ESD events making it fully capable to effectively protect the sensitive devices in the core circuit.

This paper describes a monolithic integrated transmitter intended for impulse radio (IR) Ultra-wide band (UWB) indoor communication and indoor localization. The transmitter operates in the higher UWB band centered at 7.25 GHz and generates impulses with bandwidth of 2.08 GHz. Consequently, the transmitter utilizes for communication and ranging complete UWB band assigned for Europe. The average pulse repetition frequency of 56.64 MHz and a 3-bits pulse position modulation (8-PPM) provides data rates up to 169.92 MBit/sec. Additionally, the driver amplifier with a fast switchable current bias is introduced into the transmitter for power efficient operation. The switch-on time of the bias is equal to 8ns. Besides the communication capability, an advanced time-of-arrival measurement extension is implemented in the transmitter. It runs with the clock of 3.625 GHz and allows the distance measurements with an accuracy of 275 picoseconds (translates to ranging accuracy of approximately 8.3 cm).

Both npn- and pnp-SiGe HBT types of a complementary bicmostechnology were consistently studied under mixed-mode and reverse stress conditions to check for any ageing mismatches. These were found to be more pronounced under forward than under reverse stress. Long-term stress-tests revealed a not yet described base current degradation “catching-up” under low current stress conditions. The resulting ageing parameters were put together into an ageing function for incorporation into HBT compact models.

We present for the first time a novel high resistivity bulk SiGe bicmostechnology that has been optimized for a WiFi RF front-end-IC (FEIC) integration. A nominally 1000 Ohm-cm p-type silicon substrate is utilized to integrate several SiGe HBTs for power amplifiers (PAs), a SiGe HBT low-noise amplifier (LNA), and isolated nFET RF switch device. Process elements include trench isolation for low-loss passives and reduced parasitic coupling, and a lower-resistivity region for the FETs to minimize changes to the circuit library.

This paper presents a 220-245 GHz 4 way Butler Matrix chip in 0.13μm SiGe bicmostechnology. The chip features four 230 GHz amplifiers with almost 9 dB of gain. A SP4T switch is integrated to select between the four outputs of the beamforming network. Finally, an amplifier used to compensate the losses of the SP4T is integrated. The chip exhibits 0 dB of insertion gain and draws 104 mA from 3.3 V supply mainly consumed by the amplifiers. The entire chip occupies 1.5 × 2.4 mm 2 .

In this paper, a low cost 4GS/s 8bit Folding-and-Interpolation (F&I) ADC has been demonstrated. To avoid threshold-mismatch and delay-mismatch between coarse and fine quantizer, a novel coarse quantizer with analog pre-processing circuits are proposed. According to the measurement result, the proposed coarse quantizer has successfully eliminated the glitch code. The ADC is capable of sampling analog input frequencies up to 1.5GHz with greater than 7.0 effective number of bits (ENOB) performance. The ADC has a die size of 3.8×3.8 mm 2 and consumes 4.1W of power.

A 12 bit 1.6 GS/s pipeline ADC realized in a 0.18 μm complementary bicmos SiGe process is presented. The ADC consists of a four-way time-interleaved hierarchical structure and a master-slave T/H to improve the dynamic performance of the individual sub-ADCs and to reduce both the complexity of the required interleaving background calibration algorithms and the error rate. It achieves an SFDR of 79 dBc at low frequency inputs and 66 dBc at Nyquist, and has an error rate of less than 10 -9 .

Stress investigations have been carried out on SiGe HBTs from STMicroelectronics bicmos9MW technology. The strain created by the stack of metal connections impacts the base bandgap of the transistors: from the reference to the denser dummies structure, a 9.1 meV bandgap energy variation is pointed out. Dummies structures were embedded for both DC and HF characterizations which showed a 25% increase for the collector current, and a 21% and 12% increase for the transit frequencies f T and f MAX respectively.
