Latest Patents

Freehill's latest patents include a "Monolithic I.C. implemented calibration circuit" and a "Calibration circuit for use with a differential input preamplifier in a sensor system." Both patents describe a calibration circuit that tests the integrity of the sensor, the preamplifier, and the wiring in the sensor system. The calibration circuit features first and second calibration capacitors with different capacitances connected to the preamplifier input leads. A calibration signal source is connected between the capacitors, which are preferably implemented on the same integrated circuit as the preamplifier. In operation, a calibration signal of known amplitude is applied to the calibration circuit, and the level at the preamplifier output is determined. This output level indicates certain conditions relating to the integrity of the sensor and its wiring, such as an open circuit condition or a short circuit condition.
