Patent ID: 7902857

Claim:
A reconfigurable electronic circuit, comprising: an input; an output; a voltage divider network comprising at least one fixed resistance and at least one programmable resistance; an input gate for preventing the actuation of said reconfigurable electronic circuit for input signals below a specified voltage; a means for generating a reconfiguring pulse to reprogram said programmable resistances; a first safe gate for preventing perturbation to said programmable resistances unless said first safe gate means is triggered; a logic circuit having a first logic input, a second logic input; and a logic output, wherein said first logic input of said logic circuit is electrically connected to said output of said reconfigurable electronic circuit, and wherein said second logic input of said logic circuit is used to initiate the reconfiguration of said reconfigurable electronic circuit; a programming enable gate coupled to said logic output; a second safe gate for permitting the programming of said programmable resistances when said input of said reconfigurable electronic circuit is at a specified level, and preventing the programming of said programmable resistances otherwise; means for preventing a DC offset to said means for generating a reconfiguring pulse; and an output gate, in cooperation with said voltage divider network, for switching said output of said reconfigurable electronic circuit to either of two predetermined voltage states.
