Resistor-based Temperature Sensors In Cmos Tech... -

These utilize the doped regions of the silicon substrate. They often exhibit a higher TCR but are more susceptible to noise and substrate interference.

The TCR is not perfectly linear over wide ranges (e.g., -40°C to 125°C). Designers must implement compensation circuits, often using a combination of resistors with opposite temperature coefficients, to "flatten" the error curve.

Resistor-based oscillators (where the frequency is modulated by resistance changes) allow for direct time-to-digital conversion, simplifying the analog-to-digital interface. Challenges and Trade-offs These utilize the doped regions of the silicon substrate
