Phase-compensated integrated circuit

摘要: Compensation for an effect produced by variations in the base-widths of integrated circuit transistors occurring from batch to is obtained including each a resistor resistance which has inverse relationship transistor base widths and generating phase shift signal path through transistors, depends on value such manner that relative advance with increasing values widths. A control "base-under-emitter" at output generator applied n-type island "shallow-p" formed, thereby controlling reverse bias island-resistor junction hence capacitance between ground. The associated constitute phase-advance network gyrator are arranged have base-under-emitter forming during same doping steps. also depend level further circuit, correllates this level, compensating effects would otherwise compensation.
