Abstract :
A CMOS low-voltage (1.2 V) switched buffer to be used as input stage in switched-opamp circuits is presented. The circuit is based on the use of an op-amp featuring rail-to-rail input and output swing with constant transconductance (gm) over the input common mode voltage. The circuit operates from a single 1.2 V, consuming about 0.6 mW. The total harmonic distortion is about -61 dB for 5 MHz clock frequency with 2 Vpp input amplitude
