A wideband low-noise amplifier (LNA) based on the current-reused cascade configuration is proposed. The wideband input-impedance matching was achieved by taking advantage of the resistive shunt-shunt feedback in conjunction with a parallel LC load to make the input network equivalent to two parallel RLC-branches, i.e., a second-order wideband bandpass filter. Besides, both the inductive series- and...
A low-power low-phase-noise 48-GHz CMOS LC voltage-control oscillator (VCO) and a low-power 60-GHz CMOS low-noise amplifier (LNA) for 60-GHz dual-conversion receiver are reported. The VCO dissipated 5.556 mW power, and achieved state-of-the-art phase noise of -105 dBc/Hz at 1-MHz offset from 47.84 GHz. The corresponding figure-of-merit (FOM) was -191.1 dBc/Hz, which is better than those of the reported...
A 21-27-GHz wideband low-noise amplifier (LNA) with state-of-the-art phase linearity property (group-delay-variation is only plusmn8.1 ps across the whole band) using standard 0.18 mum CMOS technology is reported for the first time. To achieve high and flat gain and small group-delay-variation at the same time, the inductive series-peaking technique was adopted in the output of each stage for bandwidth...
A 3.1-10.6-GHz ultra-wideband low-noise amplifier (UWB LNA) with excellent phase linearity property (group-delay-variation is only plusmn16.7 ps across the whole band) using standard 0.13 mum CMOS technology is reported. To achieve high and flat gain and small group-delay-variation at the same time, the inductive peaking technique is adopted in the output stage for bandwidth enhancement. The UWB LNA...
