A Novel Multifunction Digital Chip Design Based on CMOS Technology
Abstract: The realization of
an analog-to-digital-conversion chip has great significance in the applications
of electronic products. By considering mature time–number digitization, a new
multifunction digital chip with a long time delay was designed in this study on
the basis of the principle of analog-to-time conversion (ATC) and the
realization of long time delay. With additional resistance, capacitance, and
transistors, this chip can easily realize ATC, monostable triggers, Schmitt
triggers, and multivibrators. The circuit composition of this chip was
analyzed, and every module design was introduced. According to the simulation
result of Hspice and CSMC 2P2M CMOS (Complementary Metal Oxide Semiconductor)
process database, the chip layout (1mm2) design was accomplished by using CSMC
2P2M CMOS technology. Finally, the designed chip was applied in multiproject
wafer flow. The flow test demonstrated that this new chip can meet design goal
and is applicable to various digital integrated chip designs as an IP
(intellectual property) core.
