PROBLEM TO BE SOLVED: To provide a single-ended input/differential-ended output amplifier including an amplifier and a single-ended input/differential-ended output conversion circuit. SOLUTION: The present invention includes a single-ended input/differential-ended output conversion circuit, for converting an amplified signal to a differential signal pair, comprising a first transistor having a first gate coupled to a single-ended amplified signal of an amplifier, a first first terminal coupled to a second output 409 and a first second terminal coupled to a first node B; a second capacitor 406 having a second gate, a second first terminal coupled to a third output 409' and a second second terminal coupled to the second node B; a second capacitor 406 coupled between the second output and the second gate; a first resistor 403 coupled between the second output and a voltage source; a second resistor 404 coupled between the third output and the voltage source; and a current source 405 coupled between a first node and a ground.
