The differential amplifier can be implemented with BJTs or MOSFETs. A differential amplifier multiplies the voltage difference between two inputs (Vin+ - Vin-) by some constant factor Ad, the differential gain. It may have either one output or a pair of outputs where the signal of interest is the voltage difference between the two outputs.

BJT Differential Pair Osc A BJT version of the oscillator has limited voltage swing determined by the differential pair non-linearity. We can increase the voltage swing by emitter degeneration. A more popular alternative is to provide feedback capacitors. The negative conductance is decreased by the feedback factor.
