<p>PURPOSE:To enable constitution of a rectifier circuit, to improve a temperature characteristic and to obtain an operation up to a large input level by constituting a differential amplifier consisting of two transistors having different emitter size. CONSTITUTION:The emitter size of the transistor Q1 and Q2 are in the ratio of k:1. The differential amplifier consists of the transistor Q1 and Q2 and using a collector current IC2 of the transistor Q2, a characteristic of half-wave rectification is obtained.</p> |
