An 8.0 GHz to 12.2 GHz PLL with a capacitor multiplier-based active loop filter is designed in a 28 nm digital CMOS process. A passive loop filter-based version of the PLL is also implemented for comparison. While the PLL area is comparable to that of digital PLLs, the PLL performance is as good as that of an analog PLL that employs a passive loop filter. The capacitor multiplier-based active loop...
A Frequency-to-voltage converter (FVC) for use in a system for feedback linearization of VCOs is presented. The VCO linearization is intended for use in an ADC application where high resolution, low power consumption, and low voltage operation is required. These requirements places stringent demands on the performance of the FVC. The proposed implementation of the FVC is a good fit for digital CMOS...
This paper presents a low phase noise of the complementary cross-coupled voltage-controlled oscillator, which oscillates at a range of 3.64 ~ 5.37 GHz. This VCO utilizes switching capacitor modules in which eight channels are able to be selected. Moreover, MOS varactors are used as fine tuning. The fully integrated VCO provides excellent performance. The bandwidth of frequency is 1.73 GHz and the...
The next generation of wireless communication is a ubiquitous radio system concept, providing wireless access from short-range to wide-area, with one single reconfigurable and adaptive system for all envisaged radio environments. This paper presents the design approach of RCO (reconfigurable concurrent oscillator) that simultaneously generates two or more signals of different frequencies that eliminate...
