Abstract:
1. An accurate high current circuit, comprising: a) a current mirror circuit; b) a first high current circuit comprising a first plurality of transistor devices connected in parallel and a second high current circuit comprising a second plurality of transistor devices connected in parallel; c) a first high current interconnect metallization connected to the first plurality of transistor devices to receive an input current and a second high current interconnect metallization connected to the second plurality of transistor devices to connect from the second high current circuit an output current equal to said input current; d) a source voltage distribution circuit distributing a same value of said source voltage to a symmetrical array of transistor devices comprising the first plurality of transistor devices and the second plurality of transistor devices; and e) said current mirror circuit coupled to said first and second high current circuit controlling the first plurality of transistors devices to have a drain voltage equal to a reference voltage and produces from the second plurality of transistor devices said output current centered around the reference voltage.
