Title: WIDEBAND INJECTION LOCKED FREQUENCY MULTIPLIERS, OSCILLATORS AND DIVIDERS USING HIGHER ORDER LC RESONANT TANK
Abstract:
The present invention provides an injection locked frequency multiplier. The injection locked frequency multiplier comprises: an input stage, configured to receive an input signal having a first frequency, and generate a harmonic current; a resonant tank, configured to receive the generated harmonic current and flatten a phase response over a frequency band; and an output stage, configured to provide an output signal having a second frequency. The second frequency is a multiple of the first frequency. The resonant tank may be a high order resonant tank.
