Abstract
In a non-linear integration circuit, an audio sine wave signal is processed by a rectifier circuit and a smoothing circuit so that a DC output is obtained according to the amplitude of the signal. A hybrid diode which is similar in voltage-current characteristic to a silicon diode and is referred to as an 'analogous diode' is connected to the smoothing circuit, so that a DC output is obtained by means of the analogous diode in response to an abrupt change in amplitude of the input signal. The signal can be processed on a low supply voltage, and employment of the analogous diode provides an output which is similar to that which is provided by the use of a silicon diode.
