This paper presents a novel compressive particle filter (henceforth CPF) for tracking one or more targets in video using a reduced set of observations. It is shown that, by applying compressive sensing ideas in a multi-particle-filter framework, it is possible to preserve tracking performance while achieving considerable dimensionality reduction, avoiding costly feature extraction procedures. Additionally,...
In this paper a two stage CMOS Radio Frequency (RF) low noise transconductance amplifier is proposed. The feed-forward noise-cancelling technique is exploited to improve the Noise Figure (NF). Simulations with 45 nm CMOS process have been performed to verify the proposed design. The LNA achieves a transconductance of 115 mS, -3 dB bandwidth of 4.5 GHz, NF of 3.4 dB and IIP3 of -10 dBm. Compared to...
A class-AB, dual path building block for Gm-C filter that has high linearity and high PSRR is presented. The class-AB action provides good linearity and gm/Id while the dual path approach solves the PSRR problem associated with conventional class-AB OTA. A current-mode 4th order Butterworth filter designed using the proposed building block in 0.13 mum CMOS technology provides 54.2 dB IM3 and 52 dB...
