A low-power and low-voltage BBPLL-based sensor interface for resistive sensors in Wireless Sensor Networks is presented. The interface is optimized towards low power, fast start-up time and fast conversion time, making it primarily useful in autonomous wireless sensor networks. The interface is time/frequency-based, making it less sensitive to lower supply(More)
—An energy-efficient time-based sensor interface in 130nm CMOS technology is presented for resistive sensors. Traditionally resistive sensors are interfaced with a voltage divider or a Wheatstone bridge to transform the sensor signal to a voltage. However, both the voltage divider and the unbalanced Wheatstone bridge are highly affected by supply voltage(More)
