  • Patent number: 11953527
    Abstract: A peak detector comprises multiple small-size amplitude detection circuits coupled in parallel to signal inputs at which a signal is received from a VCO. Each amplitude detection circuit generates a voltage on an output, indicating a voltage peak or amplitude of a first signal input and a second signal input (specifically, differential output of VCO). At a given time, only one small-size amplitude detection circuit is activated to load VCO, reducing the impact on LC resonant frequency. The plurality of small-size detection circuits work sequentially, and an automatic averaging of their outputs can significantly improve the peak detector fluctuation (caused by process variation and device mismatch) compared to each single small-size amplitude detection circuit.
