Claim 13:
14. The image signal transmission apparatus of claim 13, wherein a zero and two poles of a frequency response of the back-stage driving circuit are determined by a plurality of circuit parameters of the back-stage driving circuit, the circuit parameters comprise a resistance Rs of each of the two load resistors, a capacitance Cd of each of the two load capacitors and a resistance 2Rd of the adjusting resistor;
wherein a transconductance of the two input transistors is gm, the zero is 1/(RsCd), a transfer function between the front-stage output signal and the back-stage output signal is (gmRs)/(1+gmRd)(1+sRsCd), and a DC gain of the back-stage driving circuit is (gmRs)/(1+(gmRd)).
