Paper Abstract
An alternative, class AB configuration of a proven class A readout cell for active/passive imaging systems is presented. Comparison between the two approaches shows that class AB circuit lowers power consumption and reduces noise by a factor of 3 while using nearly equal chip area. On the other hand, class AB has lower bandwidth because it operates at lower bias currents. A 0.5μm CMOS test chip that includes both types of readout circuits has been designed, fabricated and is currently being tested. Simulation results, using readout circuits from this test chip, are used to compare the two configurations.
