Cmos Crystal Oscillator Design. In an oscillator circuit the cmos inverter operates in the linear mode and works as an amplifier. It can be used in the normal clock circuit.
To meet the oscillating condition the crystal oscillator must provide an additional 180 degrees of phase shift. A review of manufacturers data sheets will reveal there are two types of inverting cmos gates. Cmos crystal oscillator vectron s vcc1 crystal oscillator xo is a quartz stabilized square wave generator with a cmos output.

A 10 mhz crystal oscillator was simulated in a 0 35 µm standard cmos process under cadence simulation environment. This method is base on the mechanism of decreasing the clock signal amplitude. Both of the load capacitors and were 10pf and a 1 5 v supply voltage was used. A review of manufacturers data sheets will reveal there are two types of inverting cmos gates.
