Abstract :
In this paper some techniques for continuous-time operation of low-voltage analog CMOS circuits are revisited These are based on the utilization of static, dynamic and switched floating voltage sources, on floating and quasi-floating gate transistors and on a versatile cell denoted flipped voltage follower. Circuits based on these techniques operate with a single supply voltage close to a transistor´s threshold voltage.
