Abstract :
A strobed comparator-latch designed for reproducible manufacturing has been fabricated in a development GaAs heterojunction bipolar technology (HBT) for operation to 5 Gsample/s with moderate power consumption. A conservative design approach which operates the devices well below the maximum current resulted in good circuit yield of 64% and repeatable operation at DC and at high frequency. Good agreement between measured and predicted performance was obtained, indicating that the design environment adequately represents the process
