This paper presents an interference rejection full-band UWB receiver and fast hopping carrier generator for 3.1-10.6 GHz. This receiver enables 11 bands of operation by embedding a tunable notch filter to eliminate interferers in a 5 GHz wireless local area network. The carrier generator can cover 3.1-10.6 GHz within less than 9.5 ns. The receiver, based on the proposed multi-band OFDM standard, consists of a zero-IF receive chain and required system noise figure, the receiver linearity specifications of which are discussed in this paper. It consists of a single-ended low-noise amplifier (LNA), a down-conversion mixer, a low-pass filter (LPF), and a programmable gain amplifier with an IO buffer. The LNA employs a common-gate topology of the 1st stage with dual-resonant loads, a cascade amplifier of the 2nd stage for mid-band resonance, and a tunable notch filter. The down-conversion mixer adopts a single-balanced architecture with LO cancellation. The LPF is implemented based on an active RC topology, and implements a four-stage programmable gain amplifier. The receiver dissipates 49.3 mA from a 1.8 V power supply. The average voltage conversion gain of the receiver IC is 73.5 dB, and the system noise figure is 8.4 dB. Input P1dB increases from -36.8 dBm at 4 GHz to -30.5 dBm at 10.3 GHz. The attenuation is 8.5 dB, which is achieved in the interference rejection band at 5.2 GHz. It occupies an area of 0.98 × 3.3 mm2 including the bond pads. © 2014 Springer Science+Business Media New York.
