Today's world of electronics becomes more and more digital and therefore CMOS becomes the dominant technology. A CMOS process compared to a bipolar process offers several advantages, mainly a low power consumption which is important for portable systems po ...
This thesis aims at developing wireless systems with a strong emphasis on low-power consumption and low-voltage operation. The main technical objective is the development of a single cells battery operated fully integrated CMOS RF transceiver that fulfills ...
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 ...
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 ...
A Hall sensor comprises a Hall element (1; 30; 31; 60) and an amplifier (2; 32; 33). The Hall element is placed inside the amplifier so that the current flowing through the Hall element also flows through the transistors of an amplifier stage of the amplif ...
A fast modulator for a dynamic supply linear RF amplifier has been integrated in a 0.35-μm CMOS technology. The use of this modulator with an external linear power amplifier (PA) allows to maintain its efficiency at a higher level than it would with the sa ...
A CMOS low-noise amplifier (LNA) with two variable gain ranges of 6 and 9 dB is presented. Variable gain is realized by using linearized MOS resistive circuits (MRCs) as voltage-controlled resistors. One of these resistors is located in the feedback loop o ...
The differential difference amplifier (DDA) is considered as a versatile building block for the analogue processing of floating voltages. An automatic offset compensation scheme is proposed for the DDA structure. A digital successive approximation algorith ...
