Ultra low power circuits are in high demand in many applications especially in wireless sensor networks (WSN), where energy is scavenged from environment. WSN systems contain different blocks, such as: sensors, filters, analog-to-digital converters, very o ...
Subthreshold source-coupled logic (STSCL) circuits can be used in design of low-voltage and ultra-low power digital systems. This article introduces and analyzes new techniques for implementing complex digital systems using STSCL gates with an improved pow ...

A new architecture of a Hall microsystem for low-power applications is presented. The innovation in this paper lies in the re-use of the electric current for biasing of several parts in the microsystem permitting substantial reduction of the current consum ...
Typical Low Dropout Voltage regulators (LDO), uses an error amplifier in a linear closed loop. The main advantage of such linear regulators is the low standby current due to the absence of switching. In addition, a fully integrated linear regulator with no ...
An implementation of a dynamic supply RF power amplifier (PA) in 0.11 mu m CMOS technology occupying a total area of 1.35mm(2) is presented. Two-tone measurement results at 2.4 and 5.2GHz show that the system can deliver over 16dBm linear output power with ...
This thesis presents a complete methodology for the digital calibration of analog circuits. It shows how to relax the extreme design constraints in analog circuits, allowing the realization of high-precision systems even with low-performance components. In ...
Modern applications in industry, navigation and medicine demand small and sensitive magnetic field sensors. In this thesis we have developed a new planar micro fluxgate magnetometer. High resolution, low power consumption and orthogonal fields detection ma ...
Main stream bulk CMOS and the variants of silicon-on-insulator (SOI) CMOS technologies are discussed with respect to testing for the quiescent current of mixed-signal integrated SOI circuits. The 2-3 times lower static power consumption in fully depleted C ...
An automatic offset compensation scheme for 2 stages operational amplifier is described. The presented technique can be applied to an existing OA core cell without modifying its design. Offset voltage is reduced by digitally adjusting the resulting offset ...
