A new CMOS inverter-based wideband transresistance (Rm) amplifier is proposed and analyzed. Using the Rm amplifier, tunable VHF/UHF Rm-C bandpass biquadratic filters can be designed. In these filters, the center frequency f0 can be post-tuned by adjusting the control voltages of the Rm amplifier. Experimental results have shown that the single-ended-output Rm-C bandpass biquad with the center frequency f0 = 368 MHz and the quality factor Q = 1.195 whereas the fully-differential-output configuration with Q = 360 and f0 = 222.7 MHz.
