We presented a CMOS lumped-element (LE) low-pass filter (LPF) with a group delay (GD) cancellation technique that uses parallel resonators comprising negative inductance and negative capacitance circuits. An inherent positive GD from the LEs of the LPF is canceled by a negative GD from the resonator. The LPF was implemented in the Global Foundry 8SF 130-nm RF CMOS Integrated Circuit (IC) technology. The core chip size was 1135 μm × 474 μm. The maximum passband frequency of the LPF was measured to be 1.5 GHz with a return loss of more than 10 dB, in-band loss of 0.8-2.4 dB, and out-of-band roll-off rate of 41.5 dB/GHz. The GDs at frequencies below 1 GHz were 0.31-0.33 ns and decreased to zero at 1.51 GHz. The noise figures were around 13.4-17.7 dB.
