Grounding the source of the active transistor results in the basic oscillator circuit depicted in Fig. 5.1. Transistor T2 is part of a current mirror that delivers the bias current I 0 to the active transistor T1. The latter is maintained in active mode by a resistor R 3 that forces the DC component V D0 of the drain voltage V D to be equal to the DC component V G0 of the gate voltage V G (since no current is flowing through R 3).
