Abstract
An amplifier circuit, comprising a capacitive-resistive network electrically connected between the input and output of the amplifier wherein the network provides equivalent capacitance between the input and output thereby providing frequency response compensation.
Claims2
A compensation network for reducing peaks in the output level versus frequency performance characteristics of an amplifier, comprising the combination:
- a first resistor one end of which is connected to the output of the amplifier;
- a second resistor one end of which is joined to the other end of the first resistor and the other end of said second resistor is at ground potential;
- and
- capacitively reactive means, connected between the input of the amplifier and the joined ends of the first and second resistors, for providing a reactance of at least ten times the ohmic value of the first and second resistors in parallel.
