A sub-1V CMOS DC-DC buck converter with 90% efficiency is presented in this paper. The proposed buck converter uses a digital error amplifier that can make the input voltage lower than other conventional buck converters. The buck converter uses voltage-mode control with pulse width modulation (PWM) techniques. The ramp generator of buck converter uses a Schmitt trigger circuit to replace the bias...
This article presents a CMOS receiver that works for 3-5GHz low band SC-UWB. The receiver contains PLL, Mixer, and VGA. Double down conversion is adopted in the receiver to overcome the orthogonal clock design difficulty; digital assisted RF control method is used to increase the stability. This receiver was fabricated in SMIC01.8mmRF process with chip area of 1 × 1 mm2 ;according to measurement,...
A sub-1 V CMOS low-dropout (LDO) voltage regulator with 103 nA low-quiescent current is presented in this paper. The proposed LDO uses a digital error amplifier that can make the quiescent current lower than other LDOs with the traditional error amplifier. Besides, the LDO can be stable even without the output capacitor. With a 0.9 V power supply, the output voltage is designed as 0.5 V. The maximum...
