    摘要: A switched capacitor circuit includes a first main sampler circuit, a second main sampler circuit, a first replica sampler circuit, and a second replica sampler circuit. The first main sampler circuit samples a first input of a differential input, and generates a first output corresponding to the sampled first input based on a first reference voltage. The second main sampler circuit samples a second input of the differential input, and generates a second output corresponding to the sampled second input based on a second reference voltage. The first replica sampler circuit receives the first input, and holds the received first input based on the second reference voltage. The second replica sampler circuit receives the second input, and holds the received second input based on the first reference voltage.

    摘要: A semiconductor device may include a plurality of banks; and a control unit configured to receive a command from an external device and independently control the plurality of banks according to the received command. Each bank comprises a pixel array including a plurality of pixels; a row decoder configured to activate word lines connected to the plurality of pixels under control of the control unit; a column decoder configured to activate bit lines connected to the plurality of pixels under control of the control unit; a sense amplifier and write driver configured to control and detect respective voltages of the activated bit lines to provide respective amplified voltages; and an input/output buffer configured to output data states of the pixels based on the respective amplified voltages. Related methods of operation are also discussed.

    摘要: A method for providing an anti-rollback secure timer service includes determining, at a device which includes a processor providing a trusted execution environment (TEE), a trusted memory, and a real time clock (RTC) accessible through an operating system of the device, an initial reference time value, by a secure timer application running in the TEE, the initial reference time value determined based on an initial value of the RTC obtained during booting of the device and a time delta value. The method further includes determining an updated reference time value based on the initial reference time value, a second value of the RTC, and a previously stored old reference time value, determining an updated time delta value based on the second value of the RTC and the updated reference time value, and storing the updated time delta value and the updated reference time value in the trusted memory.
