Abstract: The invention provides a voltage regulator with multiple output ranges. The voltage regulator includes a voltage divider that has at least a first resistor and a second resistor. The resistance ratio of the first resistor to the second resistor is 1:(X−1). The input of the regulator is connected to the first resistor, and the output is connected to the second resistor. A voltage source may provide a reference voltage Vref to a connecting point between the first resistor and the second resistor. At least one working circuit is connected to the output to provide the output voltage as Vout=Vin−X(Vin−Vref), wherein Vin is the input voltage. As another option, the at least one working circuit may be deactivated and the output may be coupled to ground.

Abstract: The present invention relates to an integrated circuit having a flexible reference. In an example, the integrated circuit includes a reference generator, and the reference generator can generate a flexible reference signal in response to a control signal. The flexible reference signal can be changed freely by adjusting the control signal. By providing the flexible reference, the present invention can enhance the capability of verification and characterization for an integrated circuit design and reduce the physical layout area of the integrated circuit design. The present invention also relates to a method of operating the integrated circuit with a flexible reference signal.

Abstract: The present invention provides a compact row decoder with multiple voltage support. The row decoder may include a global driver and a plurality of row-level drivers. The global driver may include one or more voltage level shifters that are operable to provide multiple voltages required to drive each of the plurality of row-level drivers. The plurality of row-level drivers each may include only one voltage level shifter. In an example, the row-level driver includes an address decoder implemented in a digital domain providing an address selection signal, a voltage level shifter to convert the address selection signal to an analog domain, and a row driver receiving driving signals from the global driver. The row driver has no voltage level shifter contained therein. Thus, the row-level drivers and the row decoder may be very compact. The present invention further provides a CMOS image sensor including the row decoder and a method of operating the CMOS image sensor.
