Abstract :
We present a fully differential two-stage Miller op-amp operating from a 0.5 V power supply. The input signal is applied to the bulk nodes of the input devices. A prototype was designed in a standard 0.18 μm CMOS process using standard 0.5 V VT devices. It has a measured 52 dB DC gain, a 2.5 MHz gain-bandwidth and consumes 110 μW.
