Further collectors may be added, the currents therein being inversely dependent on collector-emitter displacement. Plural rings may surround a single circular region, or plural collectors may be provided in a lateral transistor.  A low current applied to the further collector with an electrometer operational amplifier between it and the emitter supplies baseemitter voltage, while a linearly related increased current is applied to a further amplifier.
