Opis

A digital glitch monocycle pulse generator in a standard 0.13-mim CMOS technology is designed for breast cancer imaging system. A successful low power pulse generator is proposed whose central frequency is digitally controlled to cover 5.2 GHz. The generator is based on delay gate of Output Split Inverter (OSI). The OSI consists of an inverter with current limiting transistor which controls the biasing voltage digitally. The biasing circuit contains current mirror, PMOS transistor which enables 96.5 ps delay values. A glitch circuit is designed for a monocycle pulse width of 193 ps thought for breast cancer detection application. The proposed generator consumes 369 miw at 200 MHz pulse repetition frequency (PRF), and 1.2 V power supply voltage. Its design layout area amounts 67.2× 43.7 mim2.
