ABSTRACT
This research article presents a new design of a CMOS analog building block, termed a Four Terminal Floating Nullor Differential Input Transconductance Amplifier (FTFNDITA). This new analog building block can operate up to the MHz range and offers low-power dissipation circuitry. The proposed FTFNDITA works with ± 1.65 V power supply. Moreover, a ICs-based FTFNDITA is also developed using an off-self commercially available Current Feedback Operational Amplifier (CFOA) as IC AD844 and Operational Transconductance Amplifier (OTA) as IC LM13700 or IC CA3080. To extend the application perspective of the proposed FTFNDITA blocks, a few fundamental analog signal processing circuits like the design of Floating Inductor Simulator (FIS), First-Order Low-Pass Filter (FLPF), Floating Capacitance Multiplier (FCM), and its extension for active filter design, are incorporated. In addition, a non-ideality investigation is also performed to test the deviation between the ideal and practical design. Finally, PSPICE and experimental verifications are observed to validate the functionality of FTFNDITA.
