Abstract: A multi-rail module having mutually exclusive outputs. The module includes first and second-rail logic circuits, first and second-rail driver circuits, and a PMOS transistor sourcing VDD to both the first and second driver circuits. The first-rail logic circuit is coupled to VDD and ground and has a first logic input and a first logic output. The second-rail logic circuit is coupled to VDD and ground and has a second logic input and a second logic output. The first-rail driver circuit is coupled to ground, receives the first logic output, and has a first-rail output Q1. The second-rail driver circuit is coupled to ground, receives the second logic output, and has a second-rail output Q0. The PMOS transistor has a gate driven by a SLEEP signal.

Abstract: Methods of and systems for balancing the capacitance of a common series capacitive circuit in a semiconductor-based sensor, such as a humidity sensor, are described. Relative humidity sensors can provide measurements via a series capacitive circuit including a humidity-sensitive dielectric separating a common top plate and first and second bottom plates associated with a first and second capacitor, Cx1 and Cx2. For proper operation, the common top plate should be in capacitive balance. Capacitive balance can be achieved by creating voids within and/or along the common top plate of the sensor. A system for creating voids can include a precision cutting instrument, a measuring device for enabling the measurement of capacitance of at least one of the common series capacitive circuit, Cx1 and Cx2, and power provided from a voltage source.

Abstract: Methods of and systems providing high reliability relative humidity sensors having integrated signal conditioning are described, providing a series capacitive circuit including a humidity-sensitive dielectric, a common top plate and first and second bottom plates associated with a first and second capacitor, respectively. Changes in humidity affect the humidity-sensitive dielectric thereby causing changes in the capacitive value of said series capacitive circuit.
