    摘要: A capacitor-resistor-capacitor (CRC) element for active filter realization, which is fully integrable and compatible with MOS technology, is described. The incorporation of the CRC element in a semiconductor integrated circuit active filter also is described. The structure of the CRC filter element is closely analogous to a depletion mode MOS field effect device, except that the channel zone 26 is doped to a level which substantially precludes conductivity modulation at the usual operating voltages. However, the doping level is such as to enable the use of the channel zone as a semiconductor resistance element. Thus, the N-channel CRC element realized in the NMOS technology comprises a first capacitance composed of the gate 27, gate dielectric 38, and resistive channel 26, paralleled by the resistive channel 26 itself constituting a resistor, and then the underlying PN junction capacitance between the N-type resistive channel 26 and the underlying P-type semiconductor body portion 21. An active low-pass filter consists of two CRC elements and an operational amplifier and utilizes the positive feedback principle.

    摘要: A semiconductor device may be formed with a floating body positioned over an insulator in a semiconductor structure. A gate may be formed over the floating body but spaced therefrom. The semiconductor structure may include doped regions surrounding the floating body The floating body provides a distributed capacitance and resistance along its length to form an integrated RC circuit. The extent of the resistance is a function of the cross-sectional area of the floating body along the source and drain regions and its capacitance is a function of the spacing between the doped regions and the body and between the gate and the body. In some embodiments of the present invention, compensation for input voltage variations may be achieved.

    摘要: An integrated circuit and process for making it wherein a decoupling capacitor is provided beneath devices in the surface of the integrated circuit by the formation of a first epitaxial layer between an N substrate having a P zone diffused therein and an N device-containing epitaxial layer. A P channel diffusion to the P zone formed in the substrate will serve as a damping resistor in combination with the coupling capacitor. The process for forming such a decoupling capacitor in an integrated circuit comprises, inter alia, diffusing P impurities into the substrate to form a large junction which will subsequently function as a decoupling capacitor. A first intrinsic, P or N epitaxial layer is then grown on the semiconductor substrate. Subsequently, an N epitaxial layer is grown on the first epitaxial layer. A P channel is then driven through the N epitaxial layer and the first epitaxial layer to contact the P diffused zone which serves as the decoupling capacitor. This P channel diffusion will serve as a damping resistor in combination with the decoupling capacitor. Device diffusion, i.e., transistors, resistors, etc., will take place into the N epitaxial layer, and during growth of the epitaxial layers the P zone will significantly outdiffuse into the first epitaxial layer. Appropriate channels, isolations and contacts are also provided.
