ABSTRACT:
A voltage transfer circuit outputs an equivalent to an input voltage when enabled. Otherwise, the transfer circuit is in standby and outputs an equivalent to a standby voltage (e.g., signal ground). The voltage transfer circuit includes a switching circuit, a standby circuit, and an input-transfer circuit. The output of the transfer circuit is fed back to both the switching circuit and the input-transfer circuit. When the transfer circuit is in standby, the feedback of the output voltage provides for voltage-balancing in the input-transfer circuit, thereby reducing or eliminating leakage current in the input-transfer circuit. Similarly, when the transfer circuit is in active mode, the feedback of the output voltage provides for voltage-balancing in the standby circuit, thereby reducing or eliminating leakage current in the standby circuit.
