Abstract
A small wideband NMOS operational amplifier for high-speed LSIs was fabricated using VLSI technology with a minimum channel width of 3 ¿m and minimum gate length of 4.5 ¿m. Results such as 0.062 mm2 silicon area, 66 dB DC open-loop gain, 9.6 MHz gain-bandwidth product, +13.8/¿19.3 V/¿s slew rates and about 200 ns settling time were successfully obtained. The technique to improve transient response is also discussed.
