This is a custom generator for current mirrors that covers different options for it:

  • Pattern generation based on number of outputs and multiplier per output
  • General function for simple current mirror (options, diode connected and BS connected)
  • General function for cascoded current mirror (simple cascode, self-bias cascode with outside resistance)
  • General function for wide swing current mirror
  • Function for single unit fet (with an arbitrary 2 dim multiplier) with options as diode, BS connected and as capacitor.

This is based on top of #54 #52 #51 and #50 So please take a look on them before merging this.
Thanks,
Luighi
