Hussaini, Said (author), Jiang, H. (author), Walsh, Paul (author), MacSweeney, Dermot (author), Makinwa, K.A.A. (author)This paper presents a readout IC that uses an asynchronous charge-redistribution-based capacitance-to-digital-converter (CDC) to digitize the capacitance of a touch sensor. Thanks to the power efficient tracking algorithm, the CDC consumes negligible power consumption in the absence of touch events. To facilitate stand-alone or wake-on-touch...conference paper 2018
