A low-voltage low power square-root domain filter

Asia-Pacific Conference on Circuits and Systems, 2003
Companding filters replace g/sub m/-C filters in low voltage environments for higher dynamic range. Square-root domain filters and log-domain filters belong to this class of companding filters. The former uses the quadratic law of MOSFETs in the strong inversion region.

A Low-Power Low-Voltage Amplifier for Heart Rate Sensor

APCCAS 2006 - 2006 IEEE Asia Pacific Conference on Circuits and Systems, 2006
The demand for health-monitoring products is increasing worldwide. Low-power and low-voltage attributes are important concerns that need to be addressed in circuits used for personal health-monitoring applications, to achieve a long battery life. In this paper, a low-power low-voltage OTA used in a heart rate sensor is presented in an MOS-Bipolar ...

Design of low-power and low-voltage log-domain filters

1996 IEEE International Symposium on Circuits and Systems. Circuits and Systems Connecting the World. ISCAS 96, 2002
This paper describes a component-level mapping between linear- and log-domain filters. A modified multiple input class AB log-integrator with both f- and Q-tuning is presented. A 3/sup rd/-order elliptic filter derived from a LC ladder prototype is designed using the proposed log building blocks and including the log-domain implementation of the ...

LOW-POWER, LOW-VOLTAGE DESIGN—AN OVERVIEW

International Journal of High Speed Electronics and Systems, 1994
This paper gives an overview of design issues in low-power, low-voltage circuits. First, device and supply scaling is studied and its impact on both digital and analog circuits is described. Next, general low-power and low-voltage design strategies are presented. Finally, two examples of high-speed, low-power circuits are discussed.

Low Voltage/Low Power Microwave Electronics

30th European Microwave Conference, 2000, 2000
Simultaneous reduction in operating voltage and optimization of performance is a significant problem for portable wireless designers. Achievement of these conflicting goals requires careful consideration and design of semiconductor materials, transistor devices, circuit topologies and system architectures. Each of these issues is explored and discussed

Design of CMOS OTAs for Low-Voltage and Low-Power Application

IEICE Transactions on Fundamentals of Electronics, Communications and Computer Sciences, 2008
In this letter, two OTAs with MOSFETs operating in the weak inversion region are proposed. One of the OTAs uses the exponential-logarithm transformation algorithm. Furthermore, the other realizes the high-linearity characteristics due to a small fluctuation of the common-terminal voltage of differential pair.

A LOW-VOLTAGE LOW-POWER CMOS PHASE-LOCKED LOOP

Journal of Circuits, Systems and Computers, 2005
A low-voltage low-power CMOS phase-locked loop (PLL) is presented in this paper. It consists of a phase frequency detector, a charge pump, a loop filter, a voltage-control oscillator, and a frequency divider. A new phase frequency detector is proposed to reduce the dead zone and the mismatch effect of the charge pump circuit.

A low-power low-voltage CMOS Resistance-to-Period Converter

2012 IEEE 55th International Midwest Symposium on Circuits and Systems (MWSCAS), 2012
This paper presents a new low-power, low-voltage Resistance-to-Period Converter (RPC) for signal conditioning of resistive sensors whose equivalent resistance varies in more than one decade. Designed in a low cost 0.18 µm CMOS process, the proposed RPC attains a good compromise between linearity and power consumption, which makes it suitable for ...
