  • Publication number: 20100127331
    Abstract: Mixed gate metal-oxide-semiconductor transistors are provided. The transistors may have an asymmetric configuration that exhibits increased output resistance. Each transistor may be formed from a gate insulating layer formed on a semiconductor. The gate insulating layer may be a high-K material. Source and drain regions in the semiconductor may define a transistor gate length. The gate length may be larger than the minimum specified by semiconductor fabrication design rules. The transistor gate may be formed from first and second gate conductors with different work functions. The relative sizes of the first and gate conductors in a given transistor control the threshold voltage for the transistor. A computer-aided design tool may be used to receive a circuit design from a user. The tool may generate fabrication masks for the given design that include mixed gate transistors with threshold voltages optimized to meet circuit design criteria.

  • Publication number: 20100079200
    Abstract: A method for improving analog circuits performance using a circuit design using forward bias and a modified mixed-signal process is presented. A circuit consisting plurality of NMOS and PMOS transistors is defined. The body terminal of the NMOS transistors are coupled to a first voltage source and the body terminal of the PMOS transistors are coupled a second voltage source. Transistors in the circuit are selectively biased by applying the first voltage source to the body terminal of each selected NMOS transistor and applying the second voltage source to the body terminal of each selected PMOS transistor. In one embodiment, the first voltage source and the second voltage source are modifiable to provide forward and reverse bias to the body terminal of the transistors.

  • Publication number: 20100019351
    Abstract: A varactor may have a first terminal connected to a gate. The gate may be formed from a p-type polysilicon gate conductor. The gate may also have a gate insulator formed from a layer of insulator such as silicon oxide. The gate insulator may be located between the gate conductor and a body region. Source and drain contact regions may be formed in a silicon body region. The body region and the source and drain may be doped with n-type dopant. The varactor may have a second terminal connected to the n-type source and drain. A control voltage may be used to adjust the level of capacitance produced by the varactor between the first and second terminals. A positive control voltage may produce a larger capacitance than a negative control voltage. Application of the negative control voltage may produce a depletion layer in the p+ polysilicon gate layer.
