—A broadband, frequency-selective low-noise amplifier (LNA) with at least 25 dB of rejection at frequencies below the L-band (includes GPS and GSM carriers) is fabricated in a 90 nm standard CMOS process. The proposed LNA can be used for broadband impulse-radio ultra-wideband (IR-UWB) and frequency modulated FM-UWB. The frequency-selective (3.
In wireless receivers, large dynamic range (DR) input signals necessitate additional power consumption in baseband active filters. A 5 th order Chebychev, ladder type, companding SC low-pass filter is described in this paper which provides gain switching based on the instantaneous value of the signal to handle peak-to-average-power ratio (PAPR), thereby… (More)
