| Popis: | This article presents the design, manufacturing and test results of an on-chip CMOS oscillator, using a ring-oscillator, VCO based architecture. The oscillator generates a configurable square waveform clock signal to be used internally or externally to the IC that integrates it, with very low area (320 transistors, 112 × 148 µm) and power overhead (975 µW). The oscillator is integrated in a mixed signal IC which has been qualified for space applications, at a commercial 250 nm process. It enables the standalone operation of the IC without external oscillator and gives the possibility to clock other components and systems. In addition, it reduces the noise interference at PCB and chip level, optimising the performance of sensitive analogue parts. It was validated by radiation tests according to ESA standards’ procedures that the oscillator's functionality and characteristics do not deteriorate with TID levels up to 1Mrad. This approach can be easily adjusted to a wide range of frequencies, while significan... |
