    • An active matrix array device has a plurality of matrix array elements (100), each of which have a first capacitive device (120) coupled to a charging conductor (32m) via a first switch (100) being responsive to an addressing conductor (22n). In addition, the matrix array elements (100) comprise a second capacitive device (130) coupled to the first capacitive device (120) via a second switch (112) being responsive to en enable signal provided via an enable conductor (42n). The second capacitive device (130) is coupled to the control terminal of a third switch (114), which is coupled between the first capacitive device (120) and a potential source like the charging conductor (32m). The second capacitive device (130) is used to sample the voltage across the first capacitive device (120), which enables the third switch (114) if of an appropriate value, thus providing a conductive path between the first capacitive device (120) and the potential source. This arrangement allows for a low-power data refresh mode of the matrix array elements (100) with polarity inversion in subsequent refresh cycles.

    • An amplification circuit comprises a capacitor arrangement (42) and a switching arrangement The capacitor arrangement has a first capacitor (C2) which has a voltage-dependent capacitance and a second capacitor (C1) (which may also be voltage-dependent). The circuit is operable in two modes, a first mode in which the input voltage is provided to one terminal of at least the first capacitor, and a second mode in which the switching arrangement causes charge to be redistributed between the first and second capacitors such that the voltage across the first capacitor changes to reduce the capacitance of the first capacitor, the output voltage being dependent on the resulting voltage across the first capacitor. The invention uses a voltage controlled capacitance in combination with charge sharing between capacitors, which has the result of providing a voltage amplification characteristic. This arrangement can thus be used for the amplification of an analogue voltage, or the boosting of a fixed level (i.e. digital voltage). Thus, the circuit of the invention can be used for level shifting or amplification, for example for use in the pixels of an active matrix array device.
    • 放大电路包括电容器装置(42)和开关装置。电容器装置具有具有电压相关电容的第一电容器(C 2)和第二电容器(C 1)(其也可以是取决于电压的)。 电路可以以两种模式操作:第一模式,其中输入电压被提供给至少第一电容器的一个端子;以及第二模式,其中开关装置使电荷在第一和第二电容器之间重新分布,使得 第一电容器两端的电压改变以减小第一电容器的电容,输出电压取决于第一电容器两端产生的电压。 本发明使用电压控制电容与电容器之间的电荷共享结合起来,其具有提供电压放大特性的结果。 因此,这种布置可用于放大模拟电压,或升高固定电平(即数字电压)。 因此,本发明的电路可用于电平转换或放大,例如用于有源矩阵阵列器件的像素。
