A 5800-μm² Resistor-Based Temperature Sensor with a One-Point Trimmed Inaccuracy of ±1.2 °c (3σ) from -50 °c to 105 °c in 65-nm CMOS

This letter describes a compact resistor-based temperature sensor intended for the thermal monitoring of microprocessors and DRAMs. It consists of an RC poly phase filter (PPF) that is read out by a frequency-locked loop (FLL) based on a dual zero-crossing (ZC) detection scheme. The sensor,fabricated in 65-nm CMOS,occupies 5800 μm²...

A 0.53pJK27000μm2resistor-based temperature sensor with an inaccuracy of ±0.35°C (3σ) in 65nm CMOS

In microprocessors and DRAMs, on-chip temperature sensors are essential components, ensuring reliability by monitoring thermal gradients and hot spots. Such sensors must be as small as possible, since multiple sensors are required for dense thermal monitoring. However, conventional BJT-based temperature sensors are not compatible with the sub...
