    Photovoltaic-mode Cut-Off frequency

    For high speed operation they usually reverse bias the junction which decreases the junction capacitance, greatly improving speed, but the noise increases. Running in p-voltaic mode into a low impedance load, gets the speed up but at expense of low sensitivity. The device running into a low...

    Orcad LIB in Ascii format

    Unless you have a copy of orcad you cannot do anything with an orcad capture file as it is a binary file. If you do have a copy , you could make a schematic of a memory array for your own tests. You can get an eval version with limited capability from the Cadence website. **broken link...

    The Orcad router is actually a refined version of the 3rd party Masstec router. This was a well regarded oem router which could interface to about 20 different layout packages. This is still seen in that there are Pads and other layout package interfaces in Layout. Pads originally had a small...
