Abstract: A self-timed memory includes a plurality of write timer cells. A reference write driver circuit writes a logic low value to a true side of the write timer cells. Each write timer cell includes a pullup transistor whose gate is coupled to an internal true node. Self-timing is effectuated by detecting a completion of the logic value write at a complement side of the write timer cells and signaling a reset of the self-timer memory in response to detected completion. To better align detected completion of the write in write timer cells to actual completion of a write in the memory, a gate to source voltage of the write timer cell pullup transistor is lowered by increasing a lower logic level voltage at the internal true node in connection with driver circuit operation to write a low logic state into the true side of the write timer cell.

Abstract: In a method for recovery of a dock from a received digital data stream and an apparatus for recovering a clock from a received digital data stream, phase-shifted dock signals are generated from a receiver's dock. After selecting one of the phase-shifted clock signals, two other phase-shifted clock signals are determined. Depending on sample values taken at rising/falling edges of the three selected phase-shifted clock signals, counter values are increased and compared. The selection of phase-shifted clock signals and the steps of sampling the input digital data stream, comparing the values and increasing counter values, if required, are repeatedly performed until the comparison result of the counter values indicates that one of the latter determined phase-shifted clock signals strobes the received digital data stream in the centre of a bit period.

Abstract: A circuit includes a discharge arrangement configured to discharge an electrostatic charge. The discharge arrangement has a discharge state. A first circuit is configured to provide a pulse to the discharge arrangement when the electrostatic charge is sensed. The pulse causes the discharge arrangement to enter the discharge state. A second circuit is configured to maintain the discharge arrangement in the discharge state after the pulse has ended. A third circuit is configured to receive the pulse and to provide a delayed output to the discharge arrangement. The delayed output causes the discharge arrangement to exit the discharge state.

Abstract: A ternary content addressable memory (TCAM) is formed by TCAM cells that are arranged in an array. Each TCAM cell includes a first and second SRAM cells and a comparator. The SRAM cells predominantly in use have a horizontal topology with a rectangular perimeter defined by longer and shorter side edges. The match lines for the TCAM extend across the array, and are coupled to TCAM cells along an array column. The bit lines extend across the array, and coupled to TCAM cells along an array row. Each match line is oriented in a first direction (the column direction) that is parallel to the shorter side edge of the horizontal topology layout for the SRAM cells in each CAM cell. Each bit line is oriented in a second direction (the row direction) that is parallel to the longer side edge of the horizontal topology layout for the SRAM cells in each CAM cell.

Abstract: A battery pack management system provides information such as remaining capacity and/or run time to empty for a battery. A time taken for a battery voltage to drop a threshold amount is measured and used to determine a remaining capacity of the battery. The time may be associated with a temperature and current of the battery. The remaining capacity of a battery is calculated by monitoring a discharge of the battery. For example, current drawn from the battery is monitored over a period of time and an initial amount by which the battery has been discharged is calculated. Compensation of this initial amount is carried out in order to take into account factors such as temperature, self-discharge rate and age of the battery.

Abstract: A switched charge storage element integrator in a continuous or discrete time circuit, the integrator including a differential input amplifier, a first 2-terminal charge storage element, a second 2-terminal charge storage element, and a plurality of controlled switches. The differential input amplifier is coupled to a capacitor and a resistor and configured as an inverting integrator. An inverting terminal of the amplifier is coupled to two controlled switches. A non-inverting terminal of the amplifier is coupled to a reference voltage. The first and second switched charge storage element blocks are alternatingly coupled to the inverting terminal INM of the amplifier XOPA during the active state of a second clock signal and a first clock signal, respectively, for making the supply noise continuous and eliminating its dependency on the clock phases, thereby zeroing its convolution with the clock signal.
