Abstract :
A 16times6-bit read-only memory (ROM), employing an architecture suitable for use as a phase to amplitude converter for direct digital synthesizers (DDS), has been implemented in InP double heterojunction bipolar transistor (DHBT) technology. The ROM uses a -3.8 V power supply and dissipates 1.13 W of power. The ROM is implemented in a test circuit that includes an 8-bit accumulator and a 6-bit digital-to-analog converter (DAC) to facilitate demonstration of high-speed operation. The maximum operating clock frequency is measured to be 36 GHz
