This paper introduces a novel three-stage bandpass filter for intracardiac electrograms monitoring (IEGM), employing ferroelectric field-effect-transistor (FeFET) technology to allow bandwidth adaptation for personalized medicine. By utilizing FeFET's channel and gate stack as programmable resistor and capacitor respectively, the filter achieves precise cardiac signal isolation tailored to individual's physiological needs. Based on Globalfoundries (GF) 28 nm SLPe process that features FeFET, the design offers a broad continuous gain tuning range (22 dB to 82 dB) and bandwidth tuning range (0.1 to 25 Hz for low cut-off frequency and 10 to 120 Hz for high cut-off frequency), with an average power consumption of 393 nW, showcasing a significant stride in low-power cardiac monitoring. Moreover, input sensitivity to FeFET threshold voltage mismatch and noise characteristics are also evaluated.

In mixed-mode and analog devices, the CMOS operational amplifiers are widely employed as an essential element in recent year. The design and analysis of CMOS-based Functional Amplifiers for medical applications with low power consumption, moderate bandwidth, high gain are the main objectives of this study. With Miller Compensation, the op-amp demonstrated a gain of about 69.6 for 0.8v and 68.3 for 1.6v, bandwidth of approximately 27.9 for 0.8 and 28.5 for 1.6v, and power dissipation of around 289uW for 1.6v and 282uW for 0.8v. The circuit designs were created using the Cadence Virtuoso environment in the GPDK 90-nm CMOS technology.

This paper involves the design and integration of an ultra-low power consumption Amplitude Shift Keying (ASK) demodulator and a digital Manchester decoder for biomedical applications. The ASK demodulator is based on a common source (CS) self-biased envelope detector (ED) with a double feedback loop, succeeded by a static comparator featuring constant transistor bias with a native transistor. While the digital Manchester decoder performs clock and data recovery. The practical implementation of the work is validated through simulations, executed on a standard 65 nm CMOS technology with a 50 Kbps data rate and a carrier frequency of 570 MHz. The average current drawn from a 2.5 V power supply is less than 800 nA while the circuit operates under RF variations and modulation indices ranging from 13.5% to 100%.
