Abstract

A ±10.5 V programmable pulse generator (PPG) fabricated by highvoltage (HV) BCD CMOS technology is demonstrated, where a charge pump composed of five cascaded voltage doublers is included to boost the voltage from 2.5 V to be higher than 10 V. A crossvoltage-domain operational amplifier is proposed to carry out voltage level conversion and amplification. HV analogue switches are also proposed to change the direction of output currents. The proposed 16- channel PPG is realised on silicon, where the die area is 5.43 mm₂. Physical measurements justify that the maximum output current is 525 μA, and the largest voltage of the pulses is ±10.5 V.
