Abstract
This paper presents a pulsed ultra-wideband (UWB) transmitter with high power and efficiency. It consists of a simple switched capacitor-based relaxation oscillator for sub-carrier generation which gives distortion less carrier signal with a phase noise of 106 dBc/Hz at 1 MHz frequency. Phase-locked loop circuit with ON-OFF keying (OOK) modulator to generate FM signal within the range of UWB, i.e., 3.1–10.6 GHz. And class A power amplifier is employed for signal amplification. Proposed pulsed UWB transmitter is implemented in 45-nm CMOS process technology with a power supply of 0.9 V. Experimental results prove that the presented pulsed UWB transmitter has a transmitting range of 6–8.1 GHz with a power consumption of 3.9 mW (Laha et al. 60 GHz OOK transmitter in 32-nm DG FinFET technology, [1]).
