Aiming at realizing a CMOS-process-compatible external-component-free SoC with an on-chip solar cell and a temperature sensor, this report proposes a temperature sensor that operates at about 0.5V supply voltage and presents its simulation and measurement results. The proposed temperature sensor estimates the temperature based on the ratio of the frequency variations of two oscillators, a reference ring oscillator, whose frequency varies linearly to temperature, and a temperature ring oscillator, whose frequency varies exponentially to temperature. Results of circuit simulations and actual measurements suggest that temperature estimation is possible. |
