Quartz_stabilized_oscillator_with_electronic_gain_control
This circuit replaces the lamp(Fig. 5-18)with an electronic gain control or stabilization loop. To use this circuit, adjust the 50-Ω trimmer until 2-Vpp oscillations appear at the output of A1. Figure 5-19B is a spectrum analysis of the oscillator output. Linear Technology Corporation, 1991, AN47-50.
