Abstract
In an ECL circuit, when a potential of an input signal A changes from 'L' to 'H', an output signal D correspondingly changes from 'H' to 'L', and, at this time, an output sent from a switching stage circuit is supplied to a gate of a PMOS transistor via a control capacitor. Thereby, a base current of a pull-down transistor flows, and change of a potential of an output terminal node is promoted. An NMOS transistor receiving the potential of the output terminal node is arranged between a node and a VEE supply terminal. Therefore, when the potential changes, the current flowing through a transistor decreases, and the base current of the pull-down transistor further increases, so that the change of the output signal D is further promoted.
