An asynchronous high-throughput control circuit for proximity communication

We describe an asynchronous control circuit for interchip communication that enables high throughput proximity communication. The circuit has been fabricated in TSMC 180nm technology and operates over a wide range of coupling capacitances between the chips and over a wide range of supply voltages. At the nominal voltage of 1.8 V and a coupling capacitance of 40fF, this control circuit enables a throughput of 3 Giga token items per second for the data path
