A new method for analyzing breakdown phenomena and differentiating between damage created by hot electrons and hot holes under impact ionization induced stress within SiGe HBTs is presented. Measurements demonstrate that electrons are more effective than holes for creating impact ionization induced damage under mixed-mode stress. Lucky electrons and lucky holes can be directly observed using this approach, and the induced hot carrier current yields important insight into understanding reliability of SiGe HBTs under aggressive stress.

This paper presents a 4-bit 30GS/s binary weighted DAC in 0.25 mu m bicmostechnology. The binary weighting function was implemented in the load resistor instead of the current sources. This DAC showed 0.49 LSB and 0.57 LSB of INL and DNL respectively. 0.92pJ FOM was achieved with 3.5V of power supply at a conversion rate of 30GHz.

This paper is focused on the evaluation of SiGeC HBT varactor in bicmos technologies. First, we compare a standard collector-base junction varactor with the contribution of specific collector between a low cost SiGeC HBT module. From this, we suggest new types of structure with no additional mask which allows to keep high quality factor and to have a wide tuning range (3:1) between standard diode P+/Nwell and HBT varactor with SIC implant.

Waveguides and varactors are evaluated with their application in integrated SiGe mm-wave circuits in mind. Coplanar waveguides and hyperabrupt varactors show adequate performance when carefully designed. Waveguides with similar to 2dB/cm RF loss at 10 GHz and varactors with a tuning-range Q(min) product of 0.7 THz are demonstrated.

Large-signal compact modeling of SiGe HBTs integrated into a new IBM bicmostechnology geared towards high-efficiency Power Amplifiers is described. The technology exhibits a record 73% PAE at 5.75GHz in class AB operation. A scalable HiCUM model (High current model) is developed to accurately model the DC, small-signal and large-signal characteristics. Results of DC, f(T) characteristics, output power, PAE and AM-PM performance of the device are discussed in detail.

A novel bicmos integration scheme is described whereby high-performance, high breakdown-voltage SiGe HBTs can be integrated alongside ultra high performance, 200 GHz SiGe HBTs. The integration scheme is summarized and proof-of-concept data is shown to indicate the validity of the proposed scheme. It is shown that a 5.5V BVCEO HBT with peak F-T of 45 GHz can be manufactured on the same wafer as a 200 GHz HBT with zero or one additional masking layers.

We review the limits faced in scaling of InP-based bipolar transistors for increased device bandwidth. Emitter and base contact resistivities and IC thermal resistance are the major limits to increased device bandwidth. Devices with 1-1.5 THz simultaneous f(tau) and f(max) are feasible;these will enable 75 monolithic amplifiers and medium-scale digital ICs at similar to 400-500 GHz clock rate.

This paper presents an ultra-wideband voltage controlled oscillator (VCO) IC using 0.35 mu m SiGe bicmostechnology. The VCO IC exhibits an oscillation frequency from 2.67 to 4.37 GHz. To realize the wideband tuning range, a novel resonant circuit is proposed. The novel resonant circuit consists of three NMOS varactor pairs, p-n diodes, two spiral inductors and a control circuit which sequentially applies a control voltage to the NMOS varactor pairs and p-n diode pairs. The novel resonant circuit allows the VCO IC to have the wideband tuning range with a single analog control voltage. The dc current consumption of the VCO is 5.8 mA at a collector voltage of 4.0 V. The VCO has a phase noise of -111 dBc/Hz at 1 MHz offset at an oscillation frequnecy of 4.37 GHz.
