(1) Bridge oscillator
The bridge oscillator is a type of RC feedback circuit oscillator, and the upper frequency limit is
approximately 1 MHz. The basic part of the bridge oscillator is the lead-lag circuit of the signal phase
,
as shown in the figure. RI and cl together form the lagging part of the circuit i Rz and C2 form
the leading part of the circuit. When RI=R2, c1=C2, the attenuation of the circuit will be 1/3.
