Latest Patents

Couriol’s listed patents address two aspects of resistive sensing and oscillator design. Together, they describe techniques for measuring sensor resistance while managing circuit behavior that can affect accuracy and stability.

“Parasitic Capacitance Mitigation Circuit for Relaxation Oscillators” describes a circuit that detects voltage transients across parasitic capacitance in a resistive sensing element. A pulse generator responds to a detected transient by opening a switch across the capacitance and closing another switch to discharge it to a reference voltage node. This approach is intended to reduce the effects of parasitic capacitance on a relaxation oscillator.

“Resistive Sensor Interface” describes an analog front end that oscillates at a frequency proportional to a resistive sensor’s resistance. The interface can adjust its integrator capacitance and gain to vary the oscillation frequency. A smart digital controller computes the sensor resistance from that frequency and responds to unstable oscillation by changing the gain and integrator capacitance.
