Low Power Op-Amp Based on Weak Inversion with Miller-Cascoded Frequency Compensation A design for a rail-to-rail input and output operational amplifier is introduced. The circuit operates with 0.8 V single supply. The rail-to-rail input stage with controlled g/sub m/, is obtained by biasing...
In this paper, a power efficient gain boosting current mirror with fast stand-by recovery (4.5μs) and a maximum gain of 80dB is proposed in a 0.35μm CMOS process with 3V power supply. The gain is achieved from the aspect ratios in transistors and deployed closed loop amplifier. In act...
A fully differential high-dynamic range operational transconductance amplifier (OTA) to be used in switched- capacitor filters and/or over-sampled A/D converters is presented. The architecture chosen for this design is folded cascode with fully differential gain boosting. It is demonstrated through th...
