A RS232 transmitter interface circuit used for CMOS sensor IC has been developed in a 0.6mum CMOS technology, which makes it possible to integrate CMOS sensors and subsequent signal processing and communication interface circuits in a single chip. The positive and negative voltages (+7.6V/-6.1V under +5V single supply) are achieved with on-chip charge pump,(More)
