摘要： A non-linear interpolation circuit includes current interpolation units and an I-V converter. The current interpolation units receive an operating voltage corresponding to digital image data and corresponding reference voltages to generate corresponding operating currents. When the operating voltage changes, at least one of the corresponding current interpolation units generate the corresponding operating current, and the operating currents with respect to the operating voltage are superimposed to form an interpolation current. The I-V converter converts the interpolation current into an interpolation voltage. An interpolation current generating circuit and a method for converting digital data into analog data are also disclosed herein.

摘要： A control device for fast transient recovery of the output voltage of DC-DC converters. The control device is characterized by using a dual-threshold method to compare the actually received loading voltage values on the loading terminals of DC-DC converters, i.e., a total of four threshold levels including a negative-ripple falling-edge threshold and a negative-ripple rising-edge threshold on the negative polarity, and a positive-ripple rising-edge threshold and a positive-ripple falling-edge threshold on the positive polarity. During the transient, the load current charging/discharging control device disclosed in the invention may be switched between charging and discharging mode based on the relation between two-pairs threshold values and output voltage amplitude of DC-DC converters. This mechanism may allow DC-DC converters with higher slew rate to make transient ripples on output voltage to return to steady state more quickly.
摘要翻译：用于快速瞬态恢复DC-DC转换器输出电压的控制装置。控制装置的特征在于使用双阈值方法来比较DC-DC转换器的负载端子上的实际接收的负载电压值，即总共四个阈值电平，包括负纹波下降沿阈值和负值 - 负极性的上升沿阈值，正极性上的正纹波上升沿阈值和正纹波下降沿阈值。在瞬变期间，本发明中公开的负载电流充放电控制装置可以基于两对阈值与DC-DC转换器的输出电压幅度之间的关系在充电和放电模式之间切换。这种机制可能允许具有更高转换速率的DC-DC转换器使输出电压上的瞬态波纹更快地恢复到稳定状态。

摘要： A dual mode transient recovery control method and system is proposed, which is designed for use with a direct-current (DC) power output unit, such as a DC-DC converter, for fast transient recovery of DC output power by switching the DC-DC converter to operate between a hysteretic mode and a PWM (Pulse Width Modulation) mode. The proposed control method and system is characterized by the use of a dual-threshold scheme to compare the output voltage. This feature may discharge the transient output voltage, raised by the over-shoot, to the steady state by switching to the discharging mode, and similarly charge the transient output voltage, dropped by the under-shoot, to the steady state by switching to the charging mode. This mechanism may allow DC-DC converters with higher slew rate to make transient ripples of output voltage to return to steady state more quickly, and additionally allow a better level of noise immunity.
