Low-voltage and low-power libraries for Medical SoCs

TL;DRAbstract

The recent focus on Green Electronics and a rapid revolution of bio-chips has led to the need for designs operating with lower supply voltages and consuming lesser power than before.This thesis focuses on the design of a library of low-voltage and low-power circuit designs on TSMC 0.13 m process.A survey of existing well-known architectures for bio-medical acquisition systems is done, and some modifications to the existing system is presented.A low-voltage rail-to-rail amplifier is designed with a novel voltage-mode technique to obtain constant transconductance over the entire common-mode input range.The power consumption of this amplifier is less than 3 W .A universal figure-of-merit is established to rank a rail-to-rail input stage, taking into account the complexity in designing in sub-micron processes.This new figure-ofmerit accounts for the variation in transconductance, the maximum common-mode range possible and the power consumption.A chopper amplifier with about 33 dB gain, cap
