摘要： A game controller with a communications interface, at least one touch sensitive pad having a plurality of touch sensitive elements, and processing circuitry coupled to the communications interface and the at least one touch sensitive pad. The processing circuitry enacts touch pad configuration settings that correlate subsets of the plurality of touch sensitive elements to respective distinct user input locations. The processing circuitry receives touch pad input from the at least one touch sensitive pad. The touch pad input corresponds to a user's touch of at least some of the plurality of touch sensitive elements. The processing circuitry processes the touch pad input to determine user input directions based upon the touch pad configuration settings, and then transmits the touch pad input directions to a game console via the communications interface for use as gaming input.

摘要： The present invention provides several scalable integrated circuit high density capacitors and their layout techniques. The capacitors are scaled, for example, by varying the number of metal layers and/or the area of the metal layers used to form the capacitors. The capacitors use different metallization patterns to form the metal layers, and different via patterns to couple adjacent metal layers. In embodiments, optional shields are included as the top-most and/or bottom-most layers of the capacitors, and/or as side shields, to reduce unwanted parasitic capacitance.

摘要： Power over Ethernet (PoE) communication systems provide power and data communications over the same communications link, where a power source device (PSE) provides DC power (for example, 48 volts DC) to a powered device (PD). The DC power is transmitted simultaneously over the same communications medium with the high speed data from one node to the other node. The PSE typically includes a controller that controls the DC power provided to the PD at the second node of the communications link. The PSE controller measures the voltage, current, and temperature of the outgoing and incoming DC supply lines to characterize the power requirements of the PD. The PSE controller includes a resistorless switch to measure the current. The resistorless switch includes a sense transistor and a current mirror to allowing the PSE controller to calculate the current based upon a replica current.

摘要： A high speed data link includes transmitter equalization and (passive) receiver equalization to compensate for frequency distortion of the data link. In one embodiment, the transmitter equalization is performed with a de-emphasis circuit. The transmitter de-emphasis circuit pre-distorts an input signal to compensate for at least some of the frequency distortion in the data caused by the transmission line. The (passive) receive equalization circuit further compensates for the frequency distortion at the output of the transmission line to flatten the amplitude response of the output signal, and thereby reduce inter-symbol interference, improve media reach and improve the bit error rate (BER).

摘要： An integrated receiver with channel selection and image rejection substantially implemented on a single CMOS integrated circuit is described. A receiver front end provides programmable attenuation and a programmable gain low noise amplifier. Frequency conversion circuitry advantageously uses LC filters integrated onto the substrate in conjunction with image reject mixers to provide sufficient image frequency rejection. Filter tuning and inductor Q compensation over temperature are performed on chip. The filters utilize multi track spiral inductors. The filters are tuned using local oscillators to tune a substitute filter, and frequency scaling during filter component values to those of the filter being tuned. In conjunction with filtering, frequency planning provides additional image rejection. The advantageous choice of local oscillator signal generation methods on chip is by PLL out of band local oscillation and by direct synthesis for in band local oscillator. The VCOs in the PLLs are centered using a control circuit to center the tuning capacitance range. A differential crystal oscillator is advantageously used as a frequency reference. Differential signal transmission is advantageously used throughout the receiver.
