摘要: Abstract-Design of high-performance continuous- time filter (CTF) for analogue signal processing is presented in this paper. To demonstrate using a novel voltage-mode multiple-loop feedback (MLF) approach CTF design, 5th-order elliptic lowpass (LPF) implemented standard 0.18-µm CMOS technology. The LPF based on an inverse-follow-the-leader structure with input distribution network to generate the required transmission zeros. consumes 35 mA from single 1.8 V power supply and it has cut-off frequency 30 MHz less than 0.7 dB passband ripple more 60 stopband attenuation. In addition, 65 dynamic range achieved.
