Abstract: The disclosure provides for a method for identifying and measuring a signal pulse induced in a microcircuit due to ionizing radiation. The method comprises locating an ionizing radiation induced pulse across a microcircuit using a plurality of sensors on the microcircuit. The method further comprises radiating a radiation through the microcircuit to produce a pulse width. The method further comprises using a time to digital converter (TDC) to measure a duration of the pulse width to create a measured pulse width. The method further comprises using the TDC to convert the measured pulse width into a digital signal.

Abstract: The digital signal is provided to the digital-to-analog upconverter (40) such as through digital signal processing circuitry (70). A sample rate signal and a divided sample rate signal are provided by divider chain (96) using the clock input (44). The divided sample rate signal is used to drive the decode circuit (88). The digital outputs of the decoder circuit (88) is combined with the sample rate signal in a mixer (52) which in turn generates a digitally upconverted signal which drives a plurality of switches combined together to form the analog output (46).

Abstract: A router circuit has an electrical-to-optical converter for changing the plurality of electrical input signals into a plurality of optical input signals. A mixing circuit is coupled to the electrical-to-optical converter. The mixing circuit generates a plurality of substantially identical composite signals corresponding to the plurality of optical inputs. The composite signals comprise at least a portion of each of the plurality of optical signals. A plurality of optical bandpass filters is coupled, respectively, to each of said plurality of composite signals. The bandpass filters pass a portion of the composite optical signals to form a plurality of filtered signals. An optical-to-electrical converter is coupled to the plurality of bandpass filters. The optical-to-electrical converter converts the plurality of filtered optical signals into a respective plurality of electrical output signals.

Abstract: A digital-to-analog converter receives a stream of input words and selectively couples a plurality of current sources to produce a DAC output signal. The DAC includes a set of series-connected synchronizing switches and data switches between the current sources and the output lines, and operates the switches such that the current sources are not coupled to the data switches until the data switch transients have ended.
