Design of a 6-bit CMOS digital radio frequency memory

The authors describe the implementation of a digital radio frequency memory (DRFM) on a single integrated circuit. A VHSIC Hardware Description Language (VHDL) model of the DRFM was completed and used to design the VLSI components of the DRFM architecture. The model performed the specified time and frequency shift functions. A DRFM, with a 1 K memory, a control unit, and a digital single-sideband modulator (DSSM) has been placed onto a silicon single chip layout design.<
