    摘要: An integrated temperature-compensated RC oscillator circuit includes an inverter having an input and an output. An RC network is coupled between the inverter and a pair of comparators. A first comparator has an inverting input coupled to a first reference voltage, a non-inverting input coupled to the RC network, and an output. A second comparator has an inverting input coupled to the RC network, a non-inverting input coupled to a second reference voltage, and an output. A set-reset flip-flop has a set input coupled to the output of the first comparator, a reset input coupled to the output of the second comparator, and an output coupled to the input of the inverter. Differential amplifiers in the comparators each have a diode-connected p-channel MOS transistor controlling a mirrored p-channel MOS transistor whose channel width is less than that of the diode-connected p-channel current mirror transistor.

    摘要: An integrated circuit device includes a programmable logic block, a monitoring input, a condition-sensing circuit coupled to the monitoring input and configured to generate a condition-sensed signal at an output in response to sensing a condition at the monitoring input, a first digital input, a first digital output, and a gating circuit configured in the programmable logic block and coupled between the first digital input and the first digital output. The gating circuit has a gating input coupled to the condition-sensing circuit and generates an output. The output is related to an input state of the first digital input in the absence of the condition-sensed signal and assumes an override state in the presence of the condition-sensed signal.

    摘要: A programmable logic device (PLD) with a plurality of programmable regions is disclosed. Some of the programmable regions have switch power or ground supplies to allow them to be put into a low-power state in one or more low-power modes. At least one of the programmable regions always remains on during the low-power modes to enable the user to design custom PLD power management logic that may be placed in the always-on programmable region.
