Description/Abstract
This paper presents the design of an experimental first-order modulator with 4 quantization, fabricated in a 1.5-um space-qualified radiation-hard partially depleted sapphire (SOS) digital CMOS process. This converter architecture has been chosen investigation into the design of a range of common analog functions with two key one of technology and one environmental. First, both the architecture and the circ optimized using a variety of unconventional techniques to account for the influence bias-dependent, radiation-induced threshold-voltage shifts of up to 1V, as well as noise. Second, the circuitry is specially adapted to accommodate the floating-body type of process, wherein drain conductance varies considerably with drain bias and design techniques are directly applicable to very large-scale-integration silicon-on-design, where similar device phsics are encountered. Notwithstanding the severe the design, the fabricated circuit provides 9.7 bits of dynamic range in a 63-kHz si only degrading to 9.1 bits after 23 Mrad(Si) of total dose radiation.
