Abstract

In this paper, a fully integrated 7–9 GHz ultra-wideband (UWB) radar IC is implemented in 0.13 μm CMOS technology. For high-resolution and long-range detection, the conventional equivalent time sampling method and the local oscillator correlation receiver are used. The switching of transmitter circuitry significantly reduces power consumption. A Tx to Rx loop-back test ensures that the detection range is up to 5.6 m and that the sensitivity is -81 dBm. The actual experiments with the antenna agree well with our prediction. The chip size is 2.8 mm × 2 mm, and the current consumption is 110 mW at 1.2 V.
