2.8: Impedance and Admittance Inverters - Engineering LibreTexts
网页2022年5月22日 · Inverters are two-port networks used in many RF and microwave filters. The input impedance of an inverter terminated in an impedance \(Z_{L}\) is \(1/Z_{L}\). Impedance and admittance inverters are the same network, with the distinction being whether siemens or ohms are used to define them.
网页In an oscillator circuit, the CMOS inverter operates in the linear mode and works as an amplifier. The phase shift provided by the inverter is 180 degrees. To meet the oscillating condition, the crystal oscillator must provide an additional 180 degrees of phase shift.
