Abstract :
This chapter introduces the basic principles of low voltage universal opamp design. Universal low voltage opamps are amplifier architectures which operate with a constant-gm from rail-to-rail and can be implemented in any complementary VLSI technology. Design examples in both MOS and bipolar technologies are described. Simulation and experimental results from test chips with a 3 V supply are also discussed
