Abstract :
A novel analogue drive circuit for a liquid crystal cell has been designed. The design was realised in a 0.5 μm CMOS process and eight phase-locked channels with independent voltage control were developed. The channels were shown to produce over 5.6π optical phase shift using a ±2.5 V power supply. This drive circuit is proposed for use in portable battery operated applications where optical phase control is desired
