This paper describes a design of an inductor-less variable gain amplifier (VGA) for UWB systems in a standard digital 0.18 ??m CMOS technology. The VGA is implemented using four-stage modified Cherry-Hopper amplifier, and by changing the value of the feedback resistors in the Cherry-Hopper amplifiers, a variable gain from -17.4 dB to 52.7 dB can be obtained. The DC offset is reduced effectively by...
The implementation of complex functionality in low-power nano-CMOS technologies leads to enhance susceptibility to parametric disturbances (environmental, and operation-dependent). The purpose of this paper is to present recent improvements on a methodology to exploit power-supply voltage and temperature variations in order to produce fault-tolerant structural solutions. First, the proposed methodology...
A delay-locked loop of multi-band selector with wide-locking range and low power dissipation is presented. The architecture of the proposed delay-locked loop consists of phase frequency detector, charge pump, band selector, multi-control delay line, and start-up circuit. The multi-band selector is used to extend operation frequency of delay-locked loop by switching the multi-control delay line. The...
