QUADRATURE SIGNAL RECEIVER USING SYNCHRONIZED OSCILLATOR
摘要
<p>A system comprises a processing device, a signal generator to generate a first signal and a single receiver to receive a second signal from a capacitive sense array. The single receiver is configured to process the second signal for stylus sensing of a stylus proximate to the capacitive sense array in a first mode of operation and to process the second signal for touch sensing of a passive touch object proximate to the capacitive sense array in a second mode of operation. The second signal is unsynchronized with the first signal.</p>
