This paper presents a high-frequency frdly differential BiCMOS operational amplifier designed for use in switched-capacitor circuits. The OP amp is integrated in a 3. O-GHZ, 2~m BiCMOS process with an active die area of 1.0 mm x 1.2 mm. This BiCMOS op amp offers an infinite input resistance, a dc gain of 100 dB, a nnity-gain freqnency of 90 MHz with 45° phase margin, and a slew rate of 150 V/ ps. The differential output range is 12 V. The circnit is operated from a f 5-V power supply and… CONTINUE READING
