However, the impedance ZCM needs to be maximized to ensure that the VCM is detected accurately regardless of the electrode impedance Ze. To achieve this, a high-value pseudo-resistor RPSEUDO is used to set the gate bias of the OTA. The differential regulator also drives a replica VCO that can be injection-locked to a low-phase-noise clock derived from the wireless power supply. This high-quality clock output can be used for communication purposes at the system level.
