Current and voltage ADC using a differential pair of single-electron bipolar avalanche transistors

Radivoje Popovic, Marc Lany

Single-electron bipolar avalanche transistors (SEBATs) enable current sensing by electron counting at room temperature. Here, differential SEBAT circuits combining the functions of amplification and analog-to-digital (A/D) conversion are proposed and chara ...

Magnetic field sensor measuring a direction of a magnetic field in a plane and current sensor

Radivoje Popovic, Mirjana Banjevic

A magnetic field sensor for measuring a direction of a magnetic field in a plane comprises two sensing structures (1A 1B) that can be operated as a rotating Hall element. The two Hall elements are rotated in discrete steps in opposite directions. Such a ma ...
