Abstract :
Two low-voltage continuous-time schemes are analyzed. They are based on signal dependent floating voltage sources that maintain the op-amp input terminals very close to one of the supply rails. The analysis presented shows that both schemes can operate with single supply voltages lower than 1 V in current CMOS technology.
