A both Gaussian and sinusoidal phase-to-amplitude converter for low-power ultra-high-speed direct digital synthesizers
This paper introduces a new bipolar differential pair topology for both gaussian and sinusoidal signal shaping, to be used as a phase-to-amplitude converter alternative in low-power ultra-high-speed DDS. A DDS using this converter, with a 9-bit frequency resolution and an 8-bit amplitude resolution has been designed in a 0.13μm SiGe BiCMOS technology, with ft/fmax of 200/250GHz, and simulated up to a 20GHz operating clock frequency. It consumes 585mW under a 2.8V power supply. Simulated triangle shape allows an optimal SFDR of −44.5dBc in sinus mode and a SLRR of −43.5dBc in gaussian mode.
