The Design of the Sinusoidal Signal Generator

Abstract:

Sinusoidal signal generator is common electronic equipment. In this paper, the writer designed a kind of integrated CMOS sine signal generator, which generator uses wien bridge oscillation circuit.This generator circuit mainly constitutes by amplifier, leveled and low-pass filter circuit, which uses Cadence software to simulate and analysis its amplification circuit, in order to get a sine wave which has high performance accuracy and stability. Through simulating this generator, we can get a kind of sine wave which includes the frequency as the 1.109 kHz, the center potential as 2.5V, the amplitude as 2.58V, distortion is less than 2%, and this sine wave is more practical for the lower voltage supply system.
