In many applications, a Hall element is used for contact-less measurement such as linear and angular positions, electrical current, power and energy, etc. The Hall element fabricated by means of CMOS technology features mediocre characteristics [R.S. Popov ...
This paper presents a new Procedural Analog Design tool called PAD. It is a chart-based design environment dedicated to the design of analog circuits aiming to optimise design and quality by finding good tradeoffs. This interactive tool allows step-by-step ...
To perform a current sensing in capacitorless 1-transistor (IT) DRAMs on SOI, we have developed a sensing scheme with automatic reference generation. The reference current is generated by an adjustable current source. The electrical calibration of the refe ...
A novel technique for the continuous calibration of the sensitivity of Hall sensors is presented. Using an integrated coil and a new modulation/demodulation scheme, the sensitivity is measured and its drift eliminated. The obtained thermal drift is 50 ppm/ ...
This paper presents the application of a complete digital calibration methodology to the improvement of a Hall sensor-based current measurement microsystem. It is a step-by-step illustration of how generic calibration techniques and circuits can be used on ...
There are many inventions described and illustrated herein. In a first aspect, the present invention is a technique and circuitry for reading data that is stored in memory cells. In one embodiment of this aspect, the present invention is a technique and ci ...
A novel DAC architecture based on a sub-binary radix converter is presented. By calibrating digitally the nonlinear sub-binary converter, it is possible to use it as a high-precision, high-resolution digital-to-analog converter. The analog part of the new ...
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 ...
