Title: Negative feedback variable gain amplifier circuit and negative feedback amplifier circuit
Inventor: NISHIKAWA KENJIRO
IPC: H03H11/24
Filed: 1995-08-11
Abstract: PURPOSE: To obtain the negative feedback variable gain amplifier circuit with excellent linearity and having a large permissible maximum input level by varying mutual conductance of a feedback transistor(TR) to control a feedback amount. CONSTITUTION: One of a voltage V2 at a control terminal 81 fed to a drain terminal of a feedback TR 73 and a voltage V1 at a control terminal 79 fed to a gate terminal is controlled to change the mutual conductance of the TR 73. Through the constitution above, when the mutual conductance is increased to increase a feedback amount, the output impedance at the source is decreased inversely proportionally thereby suppressing an input voltage applied to an amplifier TR 71 when the input signal of a large amplitude is received. Thus, the permissible maximum input level is increased and low distortion is realized. Furthermore, a field effect TR, or a bipolar TR or a hetero junction bipolar TR is desirably adopted for the TR 73.
