    摘要: A Metal Oxide Semiconductor (MOS) device formed on a substrate and a method for forming the MOS device. The MOS device includes a drain region, a gate region surrounding the drain region, source regions arranged around the gate region and across from the drain region, and bulk regions arranged around the gate region and separating the source regions. The gate region is formed in a loop around the drain region. In this manner, the on-resistance (Ron) of a MOS device is decreased without also increasing the area of the MOS device.

    摘要: Circuits, methods, apparatus, and code that provide low-noise and high-resolution electronic circuit tuning. An exemplary embodiment of the present invention adjusts a capacitance value by pulse-width modulating a control voltage for a switch in series with a capacitor. The pulse-width-modulated control signal can be adjusted using entry values found in a lookup table, by using analog or digital control signals, or by using other appropriate methods. The capacitance value tunes a frequency response or characteristic of an electronic circuit. The response can be made to be insensitive to conditions such as temperature, power supply voltage, or processing.

    摘要: A control system for a mobile device comprises an audio input that generates an audio input signal. An audio amplifier amplifies the audio input signal using a gain. An adaptive gain control (AGC) module receives the audio input signal and adjusts the gain of the audio input signal. A comparing module generates a first signal when the gain is less than a threshold. A timing module determines a duration of the first signal. A selecting module communicates with the timing module and selects one of an active mode and an inactive mode of the mobile device when the duration is greater than a first period.
