Abstract

In this paper, a 3rd-order Chebyshev current-mode filter in 1.8V-$0.18{\mu}m$ CMOS parameter is designed. The core circuit of the current-mode filter is composed with the proposed voltage-controlled frequency tunable current-mode integrator. Using the proposed current-mode integrator, the cutoff frequency of the filter can be controlled and also total power consumption can be reduced. HSPICE simulation results show the cutoff frequency of the filter is controlled between 1.2MHz and 10.1MHz, and the power consumption is 2.85mW at Vdd=1.8V.

본 논문에서는 3차 체비세프 전류모드 필터가 1.8V-$0.18{\mu}m$ CMOS 파라메터로써 설계되었다. 전류모드 필터의 기본 회로는 제안된 전압제어 주파수 가변 전류모드 적분기로 구성되었다. 제안된 전류모드 적분기를 사용함으로써 필터의 차단주파수가 가변될 수 있으며 또한 전체 소비전력을 줄 일 수 있다. HSPICE 시뮬레이션 결과, 필터의 차단주파수는 1.2MHz에서 10.1MHz로 조절되었고 전체 소비전력은 1.8V 공급전압에서 2.85mW으로 확인되었다.
