Abstract
An analogue-to-digital converter comprising a plurality of stages in series, each stage including a full wave rectifier with two inputs and two outputs. Each of the inputs receives an analogue signal together with a constant current such that the full wave rectifier current reverses direction when the analogue signal reaches a predetermined level. Temperature compensation means are provided comprising voltage generators connected to the rectifier to provide a voltage bias thereto so as to enable the point of reversal of the rectifier current to remain constant over a wide range of ambient temperatures. The voltage generators have a temperature coefficient of voltage corresponding in magnitude and acting in the same sense as the bridge rectifier.
