Abstract

A variety of new current-mode continuous-time two integrator loop filter architectures incorporating dual output operational transconductance amplifiers (DO-OTA) and capacitors (C) are generated. These DO-OTA-C configurations consist of 2-6 DO-OTAs, depending on the structure and only 2 grounded capacitors. They are convenient for integration, suitable for high frequency, multifunctional, electronically tunable, of low sensitivity, simple in structure and easy to design. The selection of the filter structure and effects of DO-OTA nonidealities are discussed
