PURPOSE: An integrated circuit single ended-to-differential amplifier is provided to increase the efficiency of an integrated amplifier circuit by the reduction of the cost and size of an integrated amplifier circuit. CONSTITUTION: A single-ended differential amplification circuit(100) comprises a first amplifier(101) and a secondary amplifier(102) which creates differential power output by receiving signals to a first input terminal(106). The single-ended differential amplification circuit comprises one or more impedance having the size which is adjusted in order to offer the desirable amplification level of the signal received from a first input terminal. One or more impedances comprises first, second, and third resistors(103,104,105) having the size which is adjusted in order to provide desirable amplification level of the signals received from the first input terminal. The single-ended differential amplification circuit comprises an impedance network(107) connected between input terminals of non-inverting of the first and the second amplifiers.
