Abstract
Current scaling in a lateral transistor wherein a plurality of emitter-collector circuits are established, certain of said circuits having a different base width than certain other of said circuits. In one embodiment, separate transistors are formed, each with its own emitter and collector, each portion of each collector being spaced an equal distance from its associated emitter the base widths of the different transistors being different, such that, with the emitters coupled in common, different currents being dependent on the base width of the associated transistor. In a second embodiment, a common emitter is employed with the separate collectors formed as arcs about the emitter, the base widths between the emitter and the different collectors being different.
