Abstract

This work employs a leap-frog Gm-C structure to design a sixth-order Butterworth and elliptic bandpass filter that the cutoff frequency (Fo = 30MHz). A continuous-time differential Gm-C biquad and its corresponding voltage-mode version are elucidated, utilizing F.C.S (Floating Current Source) circuits as fundamental components. The enhanced current source architecture exhibits a streamlined configuration. It incorporates a reduced number of transistors, which facilitates optimal utilization of the chip's area and introduces a streamlined approach to circuit design. The suggested filter topology lacks a crucial resistor component, vital in achieving integration functionality. The suggested filter incorporates a grounding configuration for all capacitors, thereby mitigating the detrimental impact of parasitic effects. The filter design has been effectively realized utilizing TSMC's 0.18μm CMOS process. The findings from simulations have been provided to validate the theoretical analysis.
