In this paper, a fourth-order continuous-time follow-the-leader-feedback (FLFB) low-pass (LP) filter is presented. The outstanding FLFB noise behavior is exploited to minimize power consumption. This is achieved by means of customized implementation solutions based on combination of Active-RC/Active-gm-RC cells. The 0.18-μm CMOS prototype performs 22.5-MHz -3 dB LP frequency response. Large linearity and dynamic range were achieved resulting in 21.5-dBm in-band (iB) IIP3 and 87-μVRMS input referred iB integrated noise. The SNR for a -40 dB HD3 is 63 dB. The overall power consumption is 12.6 mW (i.e., 7 mA from a 1.8-V supply). The efficiency of the proposed technique is demonstrated by the achieved figure-of-merit (150.8 dB · J-1), which favourably compares to the state-of-the-art active-RC analog filters.
