A Low power 50 nm Technology Based CMOS Inverter with Sleep Transistor Scheme

This paper proposes a sleep transistor based minimum size inverter in BSIM4.3.0, 50nm CMOS technology with supply voltage of 1V, power dissipation of 46.28nW at 0.502V and maximum drain current of 70nA. The operating frequency is 1GHz. The disadvantage is decrease in voltage swing by 15% compared to the conventional CMOS Inverter of the same size, whereas the power dissipation is only 1.117% of...

Synthesis in 90-nm CMOS

We propose and demonstrate a 20-ps time-to-digital converter (TDC) realized in 90-nm digital CMOS. It is used as a phase/frequency detector and charge pump replacement in an all-digital phase-locked loop for a fully-compliant Global System for Mobile Communications (GSM) transceiver. The TDC core is based on a pseudodifferential digital architecture that makes it insensitive to nMOS and pMOS tr...

The Design Aspects for Ultra Low-Power, Low-Noise 90 nm CMOS Charge Sensitive Amplifier for the Active Pixel Detector

A falling particle in the digital registration systems for elementary particles active pixel detector induces electric charge, the value of which describes the parameters of the particle in the detector. Since the electric charge induced by a single particle is relatively weak, the detector signal is first processed (amplified and shaped) right in the zone of irradiation and only then transmitt...

Homodyne laser Doppler vibrometer on silicon-on-insulator with integrated 90 degree optical hybrids.

A miniaturized homodyne laser Doppler vibrometer (LDV) with a compact 90° optical hybrid is experimentally demonstrated on a CMOS compatible silicon-on-insulator (SOI) platform. Optical components on this platform usually have inadequate suppressions of spurious reflections, which significantly influence the performance of the LDV. Numerical compensation methods are implemented to effectively d...
