Abstract
Integrated communications apparatus and methods are used to receive, transmit, and operate on communications signals. A composite semiconductor structure may be formed for providing an integrated communications device that may include transceiver circuitry, data converter circuitry, and processor circuitry. The data converter circuitry may include an analog-to-digital and/or digital-to-analog data converter that is implemented at least partly using compound semiconductors (e.g., using compound semiconductor transistors for implementing comparators and/or switches in the data converter). The processor circuitry may include some circuitry that is formed from non-compound semiconductors, which is better suited than compound semiconductors to perform digital signal processing operations. The transceiver circuitry may include compound and/or non-compound semiconductor circuitry depending on the signal frequency and whether the signal is optical or electrical.
