The picture shows the low cost differentiator circuit. Usually differentiator consists of operational amplifier, but CMOS phase inverter CC4069 can also compose differentiator with good effect and low cost. Because of CMOS GATE's advantage of linear amplification, it is used to compose differentiator. In the circuit, R1 and R2 can be changed to meet the demand of frequency of amplitude. The two capacitors of 0.1μF are used as compensation to avoidunnecessary oscillation. The integrated circuit can also use GATE circuit of other phase inverter forms, but there should be no buffer, that is a single-stage gate.
