Abstract

See full text

A circuit includes at least three equally weighted drivers; a state variable generator; and an element selector. The latter is coupled to the drivers, has a first input from the generator, has a second input including a plurality of input thermometer-encoded data streams, and has an output of an equal number of thermometer-encoded output data streams supplied to the drivers. The element selector maps the second input to the output dynamically based on a value of the first input from the state variable generator, with an update rate that is no more than one half of a symbol-rate. A serializer is configured to provide serialized data at the symbol rate, with output coupled to one of the second input of the element selector and input of the drivers. The drivers have outputs that are combined to produce an output of the circuit at the symbol rate.
