Post-Production Tuning in Analog and RF Devices

Yield Improvement through Post-Production Performance Calibration in Analog/RF Devices

As the semiconductor industry continues to scale devices towards smaller process nodes, maintaining acceptable yields in the presence of process variations has become an increasingly challenging problem. Analog/RF circuits being particularly sensitive to process variations, the common defense is a conservative design approach which ensures high yield but, nonetheless, sacrifices area or perform...

Efficient Pre-Silicon Validation and Post-Silicon Tuning of Self-Healing Analog/RF Integrated Circuits

High frequency tuning mechanism using nanoplasma

The ever growing demand for reconfi gurable electronic devices at mobile form factors makes RF tunable devices and circuits increasingly important. Conventional tuning mechanisms typically rely on controlling material properties or dimensions. These are often achieved by using electrical, mechanical, or thermal approach. On the other hand, the tuning principle of this study is based on changing...

An Overview of Radio Frequency Fingerprinting for Low-End Devices

RF fingerprinting is proposed as a means of providing an additional layer of security for wireless devices. A masquerading or impersonation attacks can be prevented by establishing the identity of wireless transmitter using unique transmitter RF fingerprint. Unique RF fingerprints are attributable to the analog components (digital-to-analog converters, band-pass filters, frequency mixers and po...

A New Analog-based LO Harmonic Rejection Technique with Tunable Notch Frequency

An effective technique for mixer LO harmonic rejection in a SAW-less wideband receiver front-end is proposed. The proposed technique provides a tunable notch that can be placed at any frequency like mixer LO harmonics, to avoid the aliasing in baseband after mixing. An analog LC notch is used in a cascode transconductor, and it can reject one of the 3rd or 5th harmonics. T...
