Composite Row Driver Introduction

The composite row drive can be generated using four high voltage FETs as shown in Figure 8-88. 03 pulls the output up to Vpos and Q4 pulls the output down to

Vneg. Q1 and Q2 are used to bring the output back to ground: Q1 when the output is negative and Q2 when the output is positive. The entire circuit is controlled by using inputs A, B, and C with appropriate non-overlapping control signals.
