Shunt regulator circuit having a split output

A shunt regulator for an RFID tag chip is powered from split outputs from the RF rectifier, including a first output for providing a power delivery path to on-chip circuits and a second output for providing a discharge-regulation path. The shunt regulator includes a capacitor coupled between the fir...

description A shunt regulator for an RFID tag chip is powered from split outputs from the RF rectifier, including a first output for providing a power delivery path to on-chip circuits and a second output for providing a discharge-regulation path. The shunt regulator includes a capacitor coupled between the first output and ground. The shunt regulator further includes an input node for receiving a power supply voltage from the rectifier split outputs, a first diode having an anode coupled to the input node, a second diode having an anode coupled to the input node, a resistor divider circuit and amplifier coupled between a cathode of the first diode and ground, transistor having a control terminal coupled to an output of the resistor divider and amplifier circuit, and a current path coupled between a cathode of the second diode and ground.
