- Abstract
- A radar sensor that can detect humans beyond wall is required for fire-fighting rescue robots. In this paper, we propose a high voltage impulse generator for through the wall UWB impulse radar sensors for rescue robot application. An impulse signal of 4.2-GHz is generated by the triggered Colpitts oscillator utilizing 0.25-μm GaN/SiC HEMT power device. The simulation results show that the pick-to-pick voltage of 30-V and pulse width of about 2.2-ns are obtained while consuming 22-mA from a supply voltage of 28-V. The layout size of chip is 1-mm × 1-mm.
