Linear two-stage amplifier - uses operational amplifier and output transistor in conjunction with voltage sources to limit output and provide compensation |
摘要 |
The two stage amplifier has an operational amplifier (OV) and a transistor (T1). In particular, negative feedback is applied through the base-emitter of transistor (T1) to the converting input of amplifier (OV). A voltage limiter (D1) between the inverting input and the output of the operational amplifier (OV) limits operation of transistor (T1). Preferably, a battery or its equivalent (D2, C1, R5), is utilised to compensate for base emitter voltage. USE/ADVANTAGE - Linear amplifiers. Linear characteristics.
