27.9 A Dual-Mode DCO-PA with a Twisted 8-Shape Inductor for BLE Achieving 42% TX Efficiency at 1.6dBm and 0.29mW RX Clock
Abstract
This paper presents a 0.3 V dual-mode$(2.4 / 4.8 \text{GHz})$DCO-PA for BLE, achieving 42% efficiency in the TX mode and 0.29 mW power consumption in the RX clock mode. It features: 1) a twisted 8-shape inductor enabling octave tuning, with Class-D-like operation boosting transistor efficiency to 75%; 2) a tail transistor in the RX mode that minimizes power consumption and lowers the 1/f phase-noise corner to$\sim 40 \text{kHz}$.
