A high-speed wideband amplifier using a transconductance-transimpedance circuit technique is presented. The proposed circuit configuration results in more reliable performances than are typically obtained from designs using conventional pole-zero cancellation or peaking technique. With a 0.8 mu m, double poly, double metal, n-well CMOS technology and single 5-V power supply, the prelayout simulation of this amplifier shows a -3 dB frequency of 300MHz with a voltage gain of 14 dB when the loading capacitance is 1.5 pF.
