Abstract:
1. A proximity communication system comprising: a first chip having a transmit element formed on a surface thereof and a data transmitter formed in the first chip and driving the transmit element with a data signal, wherein the data transmitter includes a plurality of separate transmitter circuits, each of which is configured to drive data signals of a different respective amplitude to the transmit element; a second chip juxtaposed to the first chip and having a receive element formed on a surface thereof and a data receiver formed in the second chip receiving the data signal from the receive element, wherein the receive element is in at least partial alignment with the transmit element to form a communication link between the first chip and the second chip; and an alignment detector mechanism for determining a degree of alignment between the transmit element and the receive element, and for using the determined degree of alignment to adjust the performance of the communication link in compensation for the degree of the alignment between the transmit element and the receive element; wherein using the determined degree of alignment to adjust the performance of the communication link involves configuring at least one of the transmitter circuits to drive data signals to the transmit element.
