摘要

We present a 0.007 $hbox{mm}^{2}$ impulse-radio ultrawideband transmitter (TX) based on a ring oscillator capable of synthesizing pulses with both controlled center frequency and bandwidth using a single duty-cycling/trigger reference input. The TX embeds a single-phase charge-pump phase-locked loop (PLL), implemented with asynchronous logic, with 55 logic elements overall. The system, including radio frequency output buffers, consumes measured 30–45 pJ/pulse with a measured efficiency of $sim$47$%$ at 285 MHz center frequency and $V_{rm dd}$ in the range of 0.97–1.17 V. At 1.2V supply, the 130 nm CMOS TX tolerates $pm$ 10$%$ $V_{rm dd}$ variation, maintaining robust lock and controlled power spectral density (PSD) at 300 MHz center frequency, $-$19 dBm radiated power at 1 MHz pulse-repetition frequency, and a fractional bandwidth of 0.23. At 300 MHz, the system achieves a measured 100 ps RMS jitter, and without output buffers, the sole PLL logic occupies an active silicon area of 0.0045 $hbox{mm}^{2}$.
