A novel method for Ultra Wideband (UWB) receiver design in Wireless Body Area Network (WBAN) is proposed in this study. The method is based on the Improved Memetic-Algorithm (IMA), with the output Signal-toNoise Ratio of the receiver (SNRout) is optimized. By relating the target SNRout to the parameters of main components, including Low Noise Amplifier (LNA), mixer and base-band Low Pass Filter...

This paper presents an inductorless low-noise amplifier (LNA) design for an ultra-wideband (UWB) receiver frontend. A current-reuse gain-enhanced noise canceling architecture is proposed, and the properties and limitations of the gainenhancement stage are discussed. Capacitive peaking is employed to improve the gain flatness and 3-dB bandwidth, at the cost of absolute gain value. The LNA circui...

A very low voltage 9th order linear phase baseband switched capacitor (SC) filter has been designed to be used as part of a cellular GSM (Global System Mobile) receiver. A Gaussian-to-6dB filter of the order of seven is chosen and a second order function is added to reduce the group delay variations around. The filter uses a fully differential topology to increase the dynamic range and reduce t...

The design of a CMOS 22–29-GHz pulse-radar receiver (RX) front-end for ultra-wideband automotive radar sensors is presented. The chip includes a low-noise amplifier, in-phase/quadrature mixers, a quadrature voltage-controlled oscillator (QVCO), pulse formers, and baseband variable-gain amplifiers.

An ultra-low-voltage low-power switched-capacitor (SC) delta-sigma (∆Σ) modulator running at a supply voltage as low as 300 mV is presented for biomedical implant devices, e.g., cardiac pacemakers. To reduce the supply voltage, an inverter-based amplifier is used in the integrators, whose DC gain and gain-bandwidth (GBW) are boosted by a simple current-mirror output stage. The full input-feedfo...
