Abstract :
An Impulse based ultra-wide band (UWB) transceiver was designed using 130nm CMOS technology for a Bio-ranging system to improve the quality of cardiopulmonary resuscitation (CPR). It is developed to measure the depth of chest compression in CPR which is crucial factor for CPR quality using IR-UWB technology. The transmitter is composed of impulse generator and power amplifier (PA) operating at the center frequency of 530MHz and bandwidth of 140MHz. The Receiver is composed of a low noise amplifier (LNA), a mixer/integrator and a flash ADC. The fully integrated transceiver system operates with 1.5V supply voltage and occupies 7.6 mm2. The measurement results show that the proposed transceiver provides the spatial resolution within ±1.3cm while consuming total power of 35.6mW.
