This work proposes a simple method to enhance amplitude stability in Pierce crystal oscillator. The method is based on a modification of the conventional Pierce oscillator. The pro- posed topology is all-analog, yet it does not use an amplifier-based feedback loop for amplitude control, hence, it saves power, reduces complexity, and layout area. The proposed method does not adversely impact oscill... View full abstract»

• ### A CMOS-Compatible Spectrum Analyzer for Cognitive Radio Exploiting Crosscorrelation to Improve Linearity and Noise Performance

Publication Year: 2012, Page(s):479 - 492
Cited by:  Papers (14)  |  Patents (1)
| | PDF (2736 KB) | HTML

A spectrum analyzer requires a high linearity to handle strong signals, and at the same time a low NF to enable detection of much weaker signals. This is not only important for lab equipment, but also for the spectrum sensing part of cognitive radio, where low cost and integration is at a premium. Often there is a trade-off between linearity and noise: improving one degrades the other. Crosscorrel... View full abstract»

Cited by:  Papers (26)  |  Patents (2)
| | PDF (1286 KB) | HTML

The linearity of a high-resolution pipelined analog- to-digital converter (ADC) is mainly limited by the capacitor mismatch and the finite operational amplifier (OPAMP) gain in the multiplying-digital-to-analog converter (MDAC). Therefore, high resolution pipelined ADCs usually require high-gain OPAMP and large capacitors, which causes large ADC power. In recent years, various nonlinear calibratio... View full abstract»

In a conventional analog adaptive forward equalizer (FE), parasitic capacitance introduces an undesired RC pole at the output node of the equalizer. At high data rates, this pole can introduce intersymbol interference (ISI) that degrades performance. This paper considers the effect of the parasitic pole and presents two approaches to deal with the parasitic pole. The first approach uses an extra t... View full abstract»
