An ultra low power 2.4GHz CMOS VCO

10th IEEE International Conference on Electronics, Circuits and Systems, 2003. ICECS 2003. Proceedings of the 2003, 2004
A low power voltage-controlled oscillator (VCO) for IEEE 802.11b direct conversion receiver is demonstrated. The VCO is fabricated by TSMC 0.25-/spl mu/m; based on the measurement results, the tuning range is 187 MHz (7.78%); phase noise is -73.62dBc/Hz@600 kHz offset and -82.44dBc/Hz@1MHz offset at 2.4GHz.

A low-power analog CMOS vector quantizer

[Proceedings] DCC `93: Data Compression Conference, 2002
The authors describe the implementation and performance of what might be termed a 'Vector A/D Converter'. The IC stores a codebook of vectors on-chip, accepts a 16-element analog vector at the input, calculates the Euclidean distance between the input and all codevectors (referred to as global search), and outputs an 8-bit code to index the codevector ...

Low-power CMOS with subvolt supply voltages

IEEE Transactions on Very Large Scale Integration (VLSI) Systems, 2001
We first present a circuit taxonomy along the space and time dimensions, which is useful for classifying generic low-power techniques, followed by an analysis of optimal power supply and threshold voltages and transistor sizing for minimizing the energy-delay product of a class of complementary metal-oxide-semiconductor (CMOS) digital circuits.

CMOS optical receiver for low power biomedical microsystems

2017 25th Signal Processing and Communications Applications Conference (SIU), 2017
In this paper, an integrated CMOS optical receiver in which optical power delivery and optical communication realized on a single channel is proposed. Pulse Width Modulation (PWM) method is applied on the light source for transmission of the signals. Clock, data and power signals are obtained by various filtering methods.

Ultra-low power CMOS cells for temperature sensors

Proceedings of the 18th annual symposium on Integrated circuits and system design - SBCCI '05, 2005
Temperature sensors and voltage references require cells that generate both PTAT (Proportional To Absolute Temperature) and NTC (Negative Temperature Coefficient) voltages. We present a novel theoretical approach based on a 'quasi-constant' current to obtain these voltages in standard CMOS technology using no resistors. A test circuit was fabricated in

A CMOS low-power lock-in amplifier

2012 IEEE International Instrumentation and Measurement Technology Conference Proceedings, 2012
A novel analog lock-in amplifier designed in a 0.18µm CMOS process with a single supply voltage of 1:8V is presented in this paper. The proposed architecture recovers the signal of interest from noisy environments with errors below 5% for noise signals of the same amplitude as the signal of interest.

A 1GHz low power CMOS LNA

2007 International Conference on Microwave and Millimeter Wave Technology, 2007
A 1.8 V 0.18 um CMOS LNA for GPS applications has been designed and under the supply voltage, the fully differential LNA has been simulated. It provides a series of good results in Noise figure, Linearity and Power dissipation. The LNA achieves a voltage gain of 24 dB, Noise figure of 1.7 dB and Power dissipation of 9 mW. Besides, the input third-order

Low power CMOS digital design

Proceedings of the Tenth International Conference on Microelectronics (Cat. No.98EX186), 2002
This paper will first address the following issues: why a voltage transition causes power dissipation, what causes a transition, what are useful and redundant transitions, how information redundancy may reduce the number of transitions, how to statistically measure the average number of transitions (or activity).
