Capacitor structure and circuit facilitating increased frequency stability of integrated circuits |
摘要 |
A stabilizing circuit which increases the effective value of a capacitor and the structure of a monolithic capacitor are disclosed. The stabilizing circuit includes a transistor having a base electrode connected to the capacitor and an emitter electrode connected to a point at which it is desired to provide an increased effective capacitance. The capacitor structure is suitable for being included in monolithic integrated circuits having diffused isolation regions. A first plate of the capacitor is formed by a metallization layer, the second plate of the capacitor may be formed by an emitter diffusion into the isolation diffusion. A base diffusion which is conductively connected to the emitter diffusion and to the isolation diffusion facilitates connection of the second plate of the capacitor to the substrate.
