Abstract

See full text

A wireless communication device includes a pressure sensor to generate a first signal in response to a pressure variation. A variable offset capacitor is coupled in parallel with the pressure sensor. A first analog-to-digital converter (ADC) is coupled to the variable offset capacitor and to convert the first signal to a digital signal. The pressure sensor is a capacitive pressure sensor. The variable offset capacitor is a digitally controlled variable capacitor and the ADC is a low-resolution and low-power ADC.
