Abstract

Analog circuit parts in an integrated circuit, for example filters, can be equalized by a control current by equalizing an additional reference circuit part, whose equalization must be verified externally, with this control current. By using a suitably designed horizontal frequency oscillator whose equalization must also be verified, this reference circuit part can be dispensed with even in known TV receivers. Using additional control circuits in the integrated circuit, fine equalization of the various circuit parts can be carried out automatically by adding a small correction control current to each control current. As a result, the control circuits are free from problems related to background noise, interception range and component tolerances. Equalization of analog bipolar or CMOS integrated circuits.
