On-chip Mass Sensing at the Physical Limits of Nanoelectromechanical Systems

Maher Kayal, Marc Pastre, Christian Kauth

A tunable and self-regulating on-chip carbon nanotube based mass balance is presented for small-size and low-cost environmental and healthcare applications. Tube stretching and a phase-locked loop topology make the system widely universal and invariant to ...

Inversion factor based design methodology using the EKV MOS model

Maher Kayal, Marc Pastre, Andrea Ajbl

This paper presents a hierarchical design methodology based on the inversion factor (IF) as a key design parameter and the equations of the EKV MOS Model. A structured design approach is used to allow high flexibility. The efficiency of the methodology is ...

A Hall Sensor-Based Current Measurement Microsystem with Continuous Gain Calibration

Maher Kayal, Marc Pastre

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/ ...

Methodology for the Digital Calibration of Analog Circuits and Systems Using Sub-binary Radix DACs

Maher Kayal, Marc Pastre

This paper presents a methodology for digitally calibrating analog circuits and systems. Based on the detection of an imperfection by a simple comparator, a successive approximations algorithm tunes a compensation current. The latter is generated by a sub- ...
