CMOS design enhancement techniques for RF receivers. Analysis, design and implementation of RF receivers with component enhancement and component reduction for improved sensitivity and reduced cost, using CMOS technology.
Silicon CMOS Technology is now the preferred process for low power wireless communication devices, although currently much noisier and slower than comparable processes such as SiGe Bipolar and GaAs technologies. However, due to ever-reducing gate sizes and correspondingly higher speeds, higher Ft …

Real-time Adaptive Cancellation of Satellite Interference in Radio Astronomy
… years, radio astronomy has faced a growing interference problem as radio frequency (RF) bandwidth has become an increasingly scarce commodity. A programmable real-time DSP least-mean-square interference canceller was developed and demonstrated as a successful method of excising satellite …

Successive-approximation-register based quantizer design for high-speed delta-sigma modulators
… and wireless communications, medical imaging, RF receivers and high-definition video processing. A high-speed delta-sigma modulator requires that all components of the delta-sigma loop operate at the desired high frequency. For this reason, it is essential that the quantizer used in the …

A Continuous-Time Pipeline ADC with Reduced Sensitivity to Clock Jitter
… (5G) standard for cellular networks, direct RF receivers are becoming popular in applications such as cellular base stations. Such systems require analog-to-digital converters (ADC) with a high dynamic range over a large digitization bandwidth (> 500 MHz). For high-speed high-resolution ADCs …

Power-Efficient Voltage-Mode RF Front-End Using Quantized Analog Signal Processing
… real-estate and reducing overall cost for modern RF front-ends, SAW (Surface Acoustic Wave)-less RF receivers have become a popular topic recently. Unfortunately, removal of SAW filters requires the receiver to handle large blockers (e.g., above 0 dBm) without degrading the noise floor and in turn …

Analysis of RF Front-End Non-linearity on Symbol Error Rate in the Presence of M-PSK Blocking Signals
Radio frequency (RF) receivers are inherently non-linear due to non-linear components contained within the RF front-end such as the low noise amplifier (LNA) and mixer. When receivers operate in the non-linear region, this will affect the system performance due to intermodulation products, and …

Scenario-based uncertainty quantification for deep space optical communications
… Network (DSN) relies solely on radiofrequency (RF) communications. As science-driven space exploration missions become more complex, the data requirements are pushing the limits of existing communications infrastructure. Incorporating optical communications into the network offers a way to …
