A tiny, high-speed, voltage-feedback amplifier stable with all capacitive loads

A high-speed, voltage-feedback operational amplifier capable of operating from +/- 1.8 V to +/- 20 V supplies and driving infinite capacitive load is described. Silicon evaluations show 188 MHz bandwidth and 1500 V//spl mu/s slew rate. Die size is 38/spl times/46 square mils in a tiny SOT package. The part has been fabricated on a 40 V poly-emitter complementary bipolar process.
