  • Patent number: 8610616
    Abstract: Embodiments of the disclosure may generally relate to an analog to digital converter. An example analog to digital converter may include a unit capacitor array, a comparator and a control block. The unit capacitor array may include multiple capacitors coupled to one another via multiple switches under control of the control block. The comparator, having a first input and a second input, may be configured to receive a controlled voltage generated from the unit capacitor array and compare an analog voltage to the controlled voltage. The control block may be configured to selectively open or close the switches, receive a comparison result from the comparator, and generate a digital output based on the comparison result. The control block may be configured to control the switch timing of the unit capacitor array for reset, pre-charge, charge redistribution, and comparison phases, where a passive charge redistribution method may be utilized.

  • Patent number: 8436413
    Abstract: A nonvolatile floating gate analog memory cell (1) comprising a transistor having a source (2) and drain (3) formed inside a substrate or on an insulator body (not shown) and separated by a channel (4). The memory cell comprises at least one floating gate (5) formed on one side of the source and drain. (6) is a control gate formed on one side of the floating gate and connected to a first voltage (7). (8) is a back gate formed on the other side of the source and drain and connected to a second voltage (9). The channel is separated from the floating gate and the back gate by an insulation layer (10). The control gate is separated from the floating gate by an insulation layer (11) and the source and drain are isolated from the back gate, control gate and floating gate(s) by a spacer (12). The second voltage changes the intrinsic threshold voltage linearly during programming so that the programmed threshold voltage corresponds to the second voltage.

    Abstract: Techniques are generally described herein for analog to digital conversion. Some example ADC converters include a unit capacitor array coupled to a reference voltage, where the capacitor array includes multiple capacitors coupled to one another via multiple switches under control of a control block. A comparator, having a first input and a second input, is configured to receive a controlled voltage generated from the unit capacitor array and compare an analog voltage to the controlled voltage. The control block is configured to selectively open or close the switches, receive a comparison result from the comparator, and generate a digital output based On the comparison result.

  • Patent number: 8089314
    Abstract: A slew rate improved operational amplifier circuit is provided to improve the slew rates of an operational amplifier with minimal sacrifices in power dissipation and other operational amplifier parameters. To improve the slew rates of operational amplifiers, additional current sources are activated when a slewing operation is detected. The detection of slewing operations and the activation of current sources upon detection can be implemented using two comparator circuits—one for a positive slewing operation, and one for a negative slewing operation. A sub-45 nm FinFET implementation of this slew rate improvement concept was implemented and compared against slew rate optimized individual two-stage operational amplifiers. Simulations show that slew rates were significantly improved by the implementation of the comparator circuits (5590 V/?s vs. 273 V/?s), with minimal increases in power dissipation (78 ?W vs. 46 ?W).
