Abstract

In this paper a $6^{th}$ 1MHz~30MHz bandpass filter for Power line communication(PLC) modem receiver is designed using current mode synthesis method which is good to design the low-voltage and low-power filter. The designed bandpass filter is composed of cascade connecting between $3^{rd}$ Butterworth highpass filter and $3^{rd}$ Chebychev lowpass filter. As a core circuit in the current-mode filter, a current-mode integrator is designed with new architecture which can improve gain and unity gain frequency of the integrator. The gain and the unity gain frequency of the designed integrator is each 32.2dB and 247MHz. And the cutoff frequency of the designed $6^{th}$ bandpass filter can be controlled to 50MHz from 200KHz according to controlling voltage and the power consumption is 2.85mW with supply voltage, 1.8V. The designed bandpass filter was verified using a $0.18{\mu}m$ CMOS parameter.

본 논문에서는 저전압 저전력 필터 설계에 적합한 전류모드 방식을 이용하여 고속 전력선통신(PLC)모뎀 수 신단의 1MHz~30MHz 차단주파수를 갖는 6차 대역통과 필터를 설계하였다. 3차 바터워스 고역통과 필터와 3차 체비세프 저역통과 필터를 종속연결로 구성하여 대역통과 필터를 설계하였다. 필터를 구성하기 위한 핵심로써 기존의 전류미러형 적분기에 비하여 증가된 이득 및 차단주파수를 가지는 새로운 전류모드 적분기를 설계하였다. 설계된 전류모드 적분기의 이득과 차단주파수는 각각 32.2dB 및 247MHz이였다. 설계된 6차 대역통과 필터의 차단주파수는 제어전압에 따라서 200KHz에서 50MHz까지 조정이 될 수 있으며 소비전력은 공급전압 1.8V에서 2.85mW이였다. 설계된 대역통과 필터는 1.8V, $0.18{\mu}m$ CMOS 공정파라메터를 사용하여 검증되었다.
