  • Abstract
    A BiCMOS replicating current comparator for use in analogue convolutional decoders is described. The circuit operates asynchronously by means of a negative feedback mechanism that provides an accurate virtual ground for current summation and comparison. Measurements showed that the comparator operates in excess of 200MHz, features a wide dynamic range, and consumes 5.8mW from a 2.8V power supply. The active area of the die occupies 0.045mm2in 0.8µm technology.
