The BJT differential AMP with an active load • Many IC amplifiers use BJT loads in place of the load resistance, R C. • BJT load resistor is usually connected as a constant-current source with a very high resistance load (output resistance of the current source) • Higher load resistance, higher output gain. Left figure shows an AMP withApr 14, 2016 · 1. One way to find the gains is to pick a operating point, analyze at that, then perturb it a little and analyze at that. It takes separate pertubations for a common mode change and a differential mode change. For example, analyze everything at 0 V on both inputs. For common mode gain, raise each input 1 V and analyze what happens to the output. This exercise examines differential amplifier implemented with BJTs.
