Abstract
Ultra-wideband (UWB) heart-rate monitor designed in this text mainly consists of controller, pulse generator, pulse receiver, and displayer. Controller controls the pulse generating and receiving and heart-rate display. Based on the characteristics of avalanche of RF-BJT, we designed an UWB pulse generator in this paper. By simulating and debugging, we successfully obtained the bipolar UWB pulse, with the peak-to-valley voltage 6.7 V and peak-to-valley width 600 ps. The pulse generating circuit is suitable for the UWB heart-rate monitor, with its simple structure, low cost, and good performance.
