    • A sensor and method for widening a dynamic range of sensor circuitry for sensing energy, such as light energy. The sensor circuitry includes a sensor and recharge circuitry for sharing additional charge with the sensor as needed during an integration period. Readout circuitry is provided to read out, after the integration period, the sense voltage remaining across the sensor and recharge information indicating whether the recharge circuitry shared charge with the sensor during the integration period. The sense voltage and recharge information read out of the sensor circuitry is used in a function to determine the total amount of energy sensed by the sensor during the integration period.
    • 用于加宽用于感测能量的传感器电路的动态范围的传感器和方法,例如光能。 传感器电路包括传感器和再充电电路,用于在集成期间根据需要与传感器共享额外的电荷。 提供读出电路,用于在积分期间之后读出传感器周围剩余的检测电压,并在充电期间再次充电指示再生电路是否与传感器共用电荷。 在传感器电路读出的感测电压和再充电信息用于确定在积分期间由传感器感测到的总能量的功能。
