Abstract: A comparator is provided. The comparator includes a voltage generator, a buffer unit and a threshold control loop. The voltage generator has an output terminal for providing a reference voltage according to a constant current. The buffer unit provides an output signal according to a first input signal and a bias signal. The threshold control loop provides the bias signal to the buffer unit according to a second input signal, so as to regulate a transition threshold of the buffer unit to close to the second input signal. The output signal represents a compare result of the first and second input signals. The buffer unit and the threshold control loop are powered by the reference voltage.

Abstract: A circuit may sense the differential voltage across two nodes that each have a non-zero common mode voltage. The circuit may have a positive input impedance that is imposed across the nodes. An impedance compensation circuit may generate a compensation current that is delivered to the nodes that substantially cancels the loading effect of the positive input impedance. The impedance compensation circuit may generate a negative input impedance that is imposed across the two nodes that is substantially the same as the positive input impedance. The impedance compensation circuit may instead be configured to deliver the compensation current to the nodes.

Abstract: A sensor apparatus includes an array of active sensor elements arranged in columns and rows. Each sensor element is associated with a thin film access device disposed in a first current path through which an activation current is provided to activate the sensor element. Each sensor element is read through a respective second current path. The second current paths do not include the thin film access device of the first current path. As such, noise from the thin film access device is isolated from the second current paths.

Abstract: A compressor monitoring system includes current and voltage monitors, current and voltage averaging modules, a control module, and a switch. The current monitor measures a current drawn by a motor of a compressor. The current averaging module generates first and second average current values based on the current measured by the current monitor. The voltage monitor measures a utility power voltage. The voltage averaging module generates first and second average voltage values based on the voltage measured by the voltage monitor. The control module selectively generates a fault signal when a first ratio is greater than a first predetermined threshold and a second ratio is less than a second predetermined threshold. The first ratio is based on the first and second average current values. The second ratio is based on the first and second average voltage values. The switch deactivates the motor when the fault signal is generated.
