Title:
POWER EFFICIENT RADIO FREQUENCY (RF) MULTIPLIERS
Document Type and Number:
WIPO Patent Application WO/2020/117944
Kind Code:
A3
Abstract:
A frequency multiplier, which may include multiple commutator cells, for multiplying an input signal is provided. A frequency doubler is provided that includes at least one transformer. Each of the at least one transformer includes a primary and a secondary. Each secondary includes a center tap. The frequency doubler further includes at least one commutator cell. Each of the at least one commutator cell includes a first differential pair of input terminals and a second differential pair of input terminals. Each primary is connected to the first pair of differential input terminals and each secondary is connected to the second differential pair of input terminals. The frequency doubler further includes at least one current source and at least one ground. The center tap is connected to the at least one ground via the at least one current source.
