<?Pub Dtl?>A quadrature voltage-controlled oscillator was designed with back-gate coupling and embedded self body-biasing and implemented with the TSMC 0.18 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...
An integrated circuit of radio-frequency power detection by a 0.18ĭm CMOS process with the output voltage linearly proportional to the input power in decibel is presented. The target dynamic range of this radio-frequency power detector design is 40 dB with the log-error being within ±1dB. Whatever the point of view is on dynamic range or logarithmic error, the working range is from DC to 8GHz. The...
A 1.8-V 250-mA CMOS low-dropout regulator (LDO) with a current-efficiency rail-to-rail buffer to enhance load regulation is presented. The proposed buffer provides a push-pull output stage for driving pass device and pushes the parasitic pole far beyond the unity-gain frequency to improve phase margin of the LDO loop response. The proposed LDO has been implemented in a 0.35-μm CMOS process technology...
