Abstract: The operational transresistance amplifier (OTRA) is attractive to be used in circuit design, with the dual input-and-output characteristics of the well-known operational transconductance amplifier (OTA). A low-pass, band-pass, high-pass, and band-reject biquad filter using two OTRAs, three capacitors, and several resistors (or equivalent several MOS transistors) is presented through a new analytical synthesis method. Since the realized filter structure has no capacitors in feedback loops, rather precise output signals can be obtained. H-Spice simulations validate filter feasibility, low component sensitivities, null group sensitivities, and very close output accuracy between the OTRA-R-C and the OTRA-MOS-C biquad filters.
Keywords: Active filters, analog circuit design, continuous-time filters, low-pass filters, band-pass filters, high-pass filters, band-reject filters, operational trans-resistance amplifiers
