CMOS CDBA Based 6th Order Inverse Filter Realization for Low-Power Applications

This article describes a realization of higher-order Inverse Band Pass Filter (SO-IBPF) configuration for low-power applications based on Current Differencing Buffered Amplifier (CDBA) as active elements and a few passive components. The proposed structure is proficient to operate with 0.6V supply voltage, 0.45V bias voltage and dissipates 0.918mW power. To justify the practicability of the proposed design, frequency and phase response outputs are produced through PSPICE simulation using 0.18μm TSMC CMOS process parameters. The other performance investigations such as sensitivity, non-ideality, input-output noise analysis, temperature variations, Monte-Carlo analysis and percentage of total harmonic distortion (%THD) are also examined. Moreover, the proposed configuration is experimentally tested using commercially available IC AD844AN to verify the theoretical propositions and simulation results. The layout of the proposed structure is also realized with Analog Design Environment tool (ADE) of Cadence/ spectre environment.
