Abstract
A crystal oscillator includes a first PMOS (p-channel metal-oxide semiconductor) transistor having its gate, source, and drain terminals connected to a gate node, a source node, and a drain node, respectively; a DC (direct current) coupling network configured to couple the gate node to a first bias node; a NMOS (n-channel metal-oxide semiconductor) transistor having its gate, source, and drain terminals connected to a second bias node, a ground node, and the drain node, respectively; a second PMOS transistor having its gate, source, and drain terminals connected to the drain node, a power supply node, and the source node, respectively; a feedback capacitor positioned between the source node and the gate node; a shunt capacitor positioned between the source node and one of the power supply node and the ground node; and a crystal positioned between the gate node and one of the ground node and the power supply node.
