Abstract :
The amplitude and phase responses and high-frequency stability of an FET differential amplifier can be improved by compensating the parasitic source capacitance with a small capacitor between the gate and source of the input FET. This provides a significant improvement in the performance of oscillators and tuned or wideband amplifiers.
