New Triple Diodes Avoid Tracking and Large-Signal Problems

Tuning the AM-bands with tuning diodes (VVC-diodes) offers many advantages, especially in car radios. The characteristics and technology of the first member of a new generation of tuning diodes is presented. The salient features of this triple diode are its outstanding large-signal performance and the excellent tracking between the discrete diodes on the same chip. The specific characteristics of this new diode give rise to unconventional circuitry, examples of which are given.
