TI’s temperature sensor front-ends have an input multiplexer, high impedance PGA and high resolution sigma-delta modulator all integrated into a single chip. The low noise, chopper stabilized PGA ...

In this paper, a ring oscillator-based CMOS temperature sensor with nano-watt power consumption is presented for RFID applications. Unlike conventional temperature sensors based on bandgap reference ...

In this paper the supply sensitivity of low-power time-domain temperature sensors in RFID sensor tags is analyzed. A common topology of recent published temperature sensors is proposed. Three ...
