Patent ID: 7164324

Claim:
An oscillator circuit that doubles a frequency of a single-ended input signal: a first transistor comprising a first gate, a first source, and a first drain; a first PMOS transistor comprising a first PMOS gate, a first PMOS source, and a first PMOS drain, the first PMOS drain connected to ground and the first PMOS source connected to the first source; a second transistor comprising a second gate, a second source, and a second drain, the second drain connected to the first drain; a second PMOS transistor comprising a second PMOS gate, a second PMOS source, and a second PMOS drain, the second PMOS drain connected to ground and the second PMOS source connected to the second source; and an input node for inputting the input signal electrically connected to the first gate and the second PMOS gate.
