Abstract

A quadrature voltage-controlled oscillator was designed with back-gate coupling and embedded self body-biasing and implemented with the TSMC 0.18 μm 1P6M CMOS technology. Without using any extra negative bias-pin in the current-reuse structure, this embedded body-bias schema makes the switching transistors become forward body-biased in the duration of turn-on. It is not only beneficial for low-voltage operation, but also achieves a high oscillating output power (-2.5 dBm) with less supply power (2.5 mW). The percentage of frequency tuning range is 17.5% (from 4.60 to 5.48 GHz). The phase noise is -114 dBc/Hz at 1-MHz offset from the carrier frequency of 5.48 GHz.
