Abstract: A resistive sensor system includes resistive sensor pairs formed of first and second sensors of opposite sensitivity directions to a measured property. Each resistive sensor pair includes one of the first sensors having a first terminal and a second terminal, and one of the second sensors having a third terminal and a fourth terminal. The fourth terminal is coupled to the second terminal of the first sensor. The system further includes multiple noninverting switch elements, each having a noninverting output coupled to the first terminal of one the first sensors, and multiple inverting switch elements, each having an inverting output coupled to the third terminal of one of the second sensors. For each resistive sensor pair, the noninverting and inverting switch elements receive a switch signal for controlling the noninverting and inverting switch elements such that the first and second sensors are biased in opposition to one another.

Abstract: Some embodiments include a resistor that may be used in audio conversion for an ADC. The resistor may be made up of an n-well as well as a p-well polysilicons. The n-well and p-well polysilicons may include a shallow trench isolator. The n-well and p-well components may be in series with other n-well or p-well components respectively. Similarly, multiple n-well components which are in series, may be in parallel with multiple p-well components.
