Abstract
A white clip circuit, formed as an integrated circuit, includes a negative impedance converter which in use is operative to increase the sensitivity of an inverting long-tailed pair of transistors adapted to invert the signals and feed them back to the input in order to control the clip level and to enable it to be effective at a relatively low level.
