Abstract
achieve 0.03% & 0.03” Differential Gain & Phase performance on a single 3V supply. The op-amp was fabricated on a 4GHz, Dielectrically Isolated (DI), Complementary Bipolar Process. The op-amp employes a fully differential NPN & PNP input stage that can swing 300mV beyond either supply rail. A novel output stage is used to achieve Rail to Rail performance with common emitter output devices having Rsat < 10R The circuit has biasing that compensates for thermal self-heating and early-voltage effects of transistors in the absence of degeneration. PSRR is maintained at 64dB down to 2V single supply operation. A 40MHz operational amplifier (op-amp) has been built to
