A wireless RF CMOS interface for a soil moisture sensor

This paper describes a wireless RF CMOS interface for a soil moisture sensor. The mixedsignal interface is based on a 2ndorder switched capacitor, fully differential sigma-delta modulator with an effective resolution of 17-bit. The modulator bit stream output is applied to a counter as a first order...
