Two=way rectifier as integrated circuit - has controllable conversion characteristics by including difference amplifiers with controllable gain formed by push=pull transistors

摘要

The two-way rectifier circuit, is used for precision rectification of alternating voltages. It is designed as an integrated circuit with a controllable conversion characteristic. The input and the output potentials can be adjusted. The circuit contains two difference amplifier (1,2) with a high output resistance each linked to the load via a half-wave rectifier (16,26). One of the two difference amplifiers has a controllable gain. The non-inverting input of the first amplifier is connected to the inverting input of the second amplifier and vice-versa. The difference amplifiers are formed by two push-pull transistors with common emitter circuits.
