20220216872 | SLEW-RATE COMPENSATED TRANSISTOR TURNOFF SYSTEM - In a transistor turnoff system, a transistor control circuit is configured to adjust a control voltage at a transistor control output responsive to a comparison signal at a control input. The control voltage has a slew rate. A comparator has a comparator output and first and second comparator inputs. The first comparator input is coupled to the transistor control output. The comparator is configured to: provide the comparison signal at the comparator output based on a reference voltage at the second comparator input; and deactivate the transistor control circuit by changing a state of the comparison signal responsive to the control voltage falling below the reference voltage. A slew-rate compensator is configured to increase the reference voltage by a compensation voltage that compensates for a time delay of the comparator or the transistor control circuit. The compensation voltage is proportional to the slew rate. | 2022-07-07 |
20220216873 | Freeze And Clear Logic Circuits And Methods For Integrated Circuits - An integrated circuit includes a programmable logic circuit and freeze circuitry coupled to receive a freeze signal and a control signal. The integrated circuit also includes a logic circuit coupled to receive an output signal of the programmable logic circuit. The logic circuit is also coupled to receive an output signal of the freeze circuitry. The freeze circuitry causes an output signal of the logic circuit to be in a predefined logic state in response to the freeze signal being asserted during power-up of the integrated circuit. The integrated circuit also includes clear circuitry that asserts the control signal in response to a clear signal being asserted after the power-up of the integrated circuit. The freeze circuitry causes the output signal of the logic circuit to be in the predefined logic state in response to the control signal being asserted. | 2022-07-07 |
