Horizontal HALL devices: A lumped-circuit model for EDA simulators

A completely scalable lumped-circuit model for horizontal HALL devices is presented therein that can be efficiently implemented in SPICE-like EDA simulators. The model has been employed for the quantitative analysis of: (a) geometrical, (b) temperature, an ...

Integrated Hall Microsystem with Current Re-Use

Radivoje Popovic, Pavel Kejik, Predrag Drljaca

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 ...

CMOS magnetic sensors with integrated ferromagnetic parts

Radivoje Popovic, Pavel Kejik, Predrag Drljaca

The paper deals with Hall and flux-gate magnetic field sensors consisting of integrated combination of CMOS ASICs and planar ferromagnetic components. Ferromagnetic parts are made of a soft amorphous alloy, integrated at the CMOS wafer in a post-processing ...

Hall sensor and method of operating a Hall sensor

Radivoje Popovic, Giovanni Boero, Pavel Kejik, Predrag Drljaca

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 ...
