    摘要: Use of different materials for different conductive films forming plates or electrodes of one or more capacitors formed in a trench in a body of semiconductor materials allow connections to be made selectively to the plates. The films may be undercut by different etchants at respective connection apertures to avoid formation of connections or connections made by doped polysilicon of different conductivities forming connections to some plates of similarly doped polysilicon and blocking diode junctions with oppositely doped polysilicon. The blocking diodes may include a compensation implant to adjust reverse breakdown characteristics and provide transient and electrostatic discharge protection.

    摘要: A way of dynamically modifying error recovery on a communications controller to operate at the lowest power mode allowed by current error rate conditions. When operating conditions are good and a small number of errors are detected, a low power error detection/correction mode is entered saving battery life. The low power error correction mechanism runs at a slower frequency and lower power than the high power mechanism and maintains the same data rate for the controller, thus saving power. Selecting the controller error (power) mode may be externally, such as by a person using a control dial on a cellular telephone when the voice data gets too noisy. Alternatively, the selection can be automatic, a critical error level detector internally making the selection.

    摘要: A very low power logic circuit family which advantageously provides 1) retained high performance, 2) significantly reduced power dissipation, and 3) enhanced noise immunity. In a first set of embodiments, dual rail complementary logic signals are utilized to improve circuit immunity to external noise and to reduce noise generated by the logic circuit itself. A receiver portion of the present invention comprises two input FETs having cross coupling of the two gates to the two sources. In one preferred embodiment, both receiver and driver portions are connected in a repeater with all N channel drivers. A second set of embodiments have a single sided input in an unbalanced receiver comprising cross coupled source to gate N channel and cross coupled drain to gate P channel output transistors.

    摘要: A method for forming mixed high voltage/low voltage (HV/LV) transistors for CMOS devices is disclosed. In an exemplary embodiment, depletion of the gate conductor is controlled by leaving a fixed region of the gate conductor intrinsic, or lightly doped, thus separating the heavily doped low resistivity portion of the electrode with an intrinsic region by use of a conducting dopant barrier. The barrier is conductive in nature, but acts as a well-controlled diffusion barrier, stopping the “fast” diffusion which normally takes place in polysilicon, and eliminating diffusion between the conductors. Thereby, the device performance may be precisely predicted by carefully controlling the gate conductor thickness.

    摘要: An integrated circuit such as an ASIC device having partitioned functional units with independent threshold voltage control. A first partition is always operated in a normal mode, while subsequent partitions are maintained in a standby mode until a transition is detected at the input of the first partition. The subsequent partitions are switched to the normal mode by lowering the body voltage applied to the devices with each partition. A pulse stretcher is used to keep a partition in a normal mode for a predetermined period of time after the transition is detected.

    摘要: An off-chip driver circuit including an enhancement PFET, a depletion PFET, a depletion NFET and an enhancement NFET connected in series. The large enhancement PFET and large enhancement NFET turn off the OCD in tri-state and to turn off the unused half of the OCD to prevent overlap current when driving a ‘0’ or a ‘1’. A first gate signal is applied to the gate of the enhancement PFET and a second gate signal is applied to the enhancement NFET. A fixed voltage is connected to the gate of the depletion NFET and ground to gate of the depletion PFET. An output signal is obtained from a node between the depletion PFET and depletion NFET devices. In another embodiment, a reflection/overshoot sensor 60 is added. The output of sensor is connected to the body of a depletion PFET and an NFET. The feedback from sensor is such that the threshold voltage of the depletion devices are made more positive if the sensor detects that the output is being over-driven. A more positive threshold voltage will reduce the driver's IDS, but leaves the device in the linear mode.
