ABSTRACT:
The cascode feed forward amplifier is modified to correct alpha-induced error. A pair of resistors are serially disposed between the bases of a pair of common-base amplifiers to generate an error voltage proportional to the input signal. The error voltage is applied to the correction amplifier to provide an appropriate correction current.
