Development and research of MIS varicaps with charge transfer

Аннотация

A new type of a double-electrode MIS varicap with a carrier transfer has been proposed. It is shown that in a device of this type, there are no negative effects associated with the processes of thermal generation and accumulation of minority carriers. This makes it possible to increase the limiting frequency and improve the temperature stability of varicap operation. Two designs of the device are considered. The characteristics of the varicaps that were measured experimentally agree with the results of the calculations.
