This paper presents a current driver for an integrated angular acceleration sensor readout circuit. The architecture of the proposed amplifier consists of a voltage follower and an inverting amplifier to achieve a differential output. The amplifier and the follower are based on a three-stage class AB operational amplifier with a power output stage. The output current of current driver is controlled by input voltage and has a maximum value of 80 mA. The proposed circuit is designed in 0.18 mu m CMOS technology. The typical output current flow in an equivalent sensor load of 50 Ohm is 10 rnA with a rise time of 40 ns.
