Resistor network generation from point-to-point resistance values

Abstract:

The technology disclosed generates resistor values for networks with more than four terminals. In this case, all resistors in the network can be found by updating point-to-point (P2P) values as the network is reduced. To find the resistor value R.sub.AB between two terminals, A and B, the other terminals are effectively shorted together, reducing the network. Such reduction does not affect R.sub.AB. The point-to-point (P2P) resistance values are recalculated as other terminals are shorted. Once reduced to four terminals, the P2P resistance values are sufficient to determine R.sub.AB. Given six P2P resistance values, it generates the six resistor values required for the resistor network connecting the four terminals.
