Amplifying circuit for an integrated circuit with low-noise characteristic

摘要: An amplifying circuit is suitable for an integrated that has a characteristic of low-noise, high-gain, and low-consumptive current. In the circuit, transistors or FETs are used as elements. A basic employing transistors, forms differential pair first second resistors connected to each collector constant current source common emitter comprises third transistor, which connecting point resistors, condenser between transistor resistor, base voltage wherein outputs obtained from transistor.
