A highly compact continuous-time transimpedance low-pass filter (TILPF) topology is proposed that achieves a low input impedance and a 2nd-order transfer function in a single stage. This is suitable to perform current-to-voltage conversion with a built-in filtering characteristic in a passive mixer based wireless receiver. A 4th-order Butterworth prototype is designed with a cascade of the proposed TILPF and a self-coupled source follower based biquad in a 65nm CMOS. Operating with a 1.3V… CONTINUE READING
