Abstract :
A transistorised differential amplifier based on the feedback pair is described. A preliminary analysis is given and the results are compared with measurements over the frequency range 15kc/s¿30Mc/s. At the centre of the band the common-mode rejection ratio was 270 : 1. The effects of resistor tolerances and the accurate balancing of the two input impedances are discussed.
