Abstract

A 2.4 GHz integer-N frequency synthesizer is purposed in tsmc 0.18-μm CMOS process. The purposed design can be used for the IEEE 802.15.4a unlicensed ultra-wideband healthcare applications such as body sensor network to wireless connect with computer network. Electrocardiogram (ECG) is the important physiological parameters in human body. Through monitoring and analyzing ECG, the current-switching differential Colpitts VCO by charge pump linearization technique can know the health condition of human body and achieve the purpose of prevention and diagnosis for diseases accordingly. In this paper, a solution of this design with a discrete-time sample-hold-reset loop filter build in human body for monitoring ECG signal detection is purposed.
