Feedback Amplifier (4 Types Using FET & Transistors) Manufacturer,Supplier and Exporter in India
Product Code : SCL-EELE-12324
Indian Lab Suppliers supplies the Feedback Amplifier (4 Types Using FET & Transistors) (Product ID: 12324) as part of its electronics engineering lab equipment range. It covers the four negative-feedback amplifier types, two built with transistors and two with FETs.
Quick Answer
Voltage-shunt and current-shunt feedback amplifiers use bipolar transistors, while voltage-series and current-series amplifiers use FETs. Each of the four independent circuits has a toggle switch to connect or remove feedback, so gain, bandwidth and impedances can be compared with and without it. Three NPN transistors and two FETs are fitted, powered by an internal 12 V DC, 100 mA IC-regulated supply. An audio frequency generator and a dual-trace 20 MHz CRO are required.
