Introduction
Signal Processing
Adding signal processing electronics to the basic sensor element increases the functionality of NVE’s
sensors. The large output signal of the GMR sensor element means less circuitry, smaller signal errors,
less drift, and better temperature stability compared to sensors where more amplification is required to
create a usable output.
For the GMR Switch products, NVE adds a simple comparator and output transistor circuit to create
the world’s most precise digital magnetic sensor. For these products, no amplification of the sensor’s
output signal is necessary. A block diagram of this circuitry is shown in the figure below:

The GMR Switch holds its precise magnetic operate point over extreme variations in temperature and
power supply voltage. This low cost product has revolutionized the industrial control position sensing
market.
Taking this approach one step further, NVE’s integrated GT Sensor products add low-gain
amplification and magnet compensation circuitry to the basic sensor element to create a powerful gear
tooth and encoder sensor at an affordable price.
NVE also offers certain peripheral IC products to help customers integrate GMR sensor elements into
their systems and meet rigorous regulatory agency requirements for safety and survivability. These
products include power switch ICs for switching large currents in industrial applications and voltage
regulator ICs for reducing wide ranging automotive and industrial voltage supplies to manageable IC-
friendly levels. Both of these product types retain a “bulletproof” appearance to the outside electrical
world and resist damage from high voltage transients, reverse battery connections, and ESD/EMC
events.
For applications where a unique product is required, NVE’s in-house IC design group regularly does
custom designs for our customers. These designs range from simple variations on NVE’s existing parts
to full custom chips for one-of-a-kind applications. For applications where a unique electronic
functionality is required, please contact NVE.
