The present invention relates to a ring voltage generation circuit for generating a ring voltage (VTR) between a TIP lead (9) and a RING lead (10) with minimized power loss for electronic subscriber circuits, comprising:a) an amplifier circuit (2) which receives an input voltage (VI) for amplifying the input voltage (VI) to provide the ring voltage (VTR); b) an absolute value generator (3) which receives the input voltage (VI), measures an absolute value (|VI|) of the input voltage (VI) and outputs the measured absolute value (|VI|) of the input voltage (VI); c) a DC/DC converter (4) which receives the measured absolute value (|VI|) of the input voltage (VI) and converts the measured absolute value (|VI|) of the input voltage (VI) into a supply voltage (VSUPPLY) for the amplifier circuit (2); and d) a common mode feedback device (5) which receives the supply voltage (VSUPPLY), a TIP potential (VT) of the TIP lead (9) and a RING potential (VR) of the RING lead (10) and which generates thereof a control voltage (VC), whereas the common mode feedback device (5) controls the amplifier circuit (2) by means of the control voltage (VC)
