this astable circuit, called ring oscillator, is widely used in PLLs or as clock signal in digital circuits. The oscillator consists of a chain of odd number of CMOS inverters that generate an oscillation with a period T equal to 2* N* tp, where N is the number of inverters, and tp is the propagation delay (2 because each inverter switches twice during one period). For a tp equal to 25ps and N=11 we get an oscillation frequency of about 2 GHz
Thank you kind sir this is VERY helpful for practicing my circuits!
how to make this circuit run between 3Ghz – 3.2Ghz,
