A circuit (1) for converting first and second differential input signals into an output signal is provided with a first differential input stage (10) comprising first and second inputs (11,12) for receiving the first differential input signal and comprising first and second outputs (13,14) and with a second differential input stage (20) comprising third and fourth inputs (21,22) for receiving the second differential input signal and comprising third and fourth outputs (23,24) and with an output stage (30) comprising a first terminal (31) connected to the first output (11) that is further connected to the third output (21) and comprising a second terminal (32) connected to the second output (12) that is further connected to the fourth output (22) and comprising a third terminal (33) for providing the output signal, to avoid complex operational amplifiers. The differential input stages (10,20) comprise two pairs of transistors (15,16,25,26) and the output stage (30) comprises a current mirror with a third pair of transistors (34,35). A regulator (4) comprises the circuit (1) and a modulator stage (40) for in response to the output signal modulating a voltage supply signal.
