An amplifier, electronic display system, and a related method for generating a low power signal with an operational amplifier are disclosed herein. An embodiment of the present invention includes an amplifier, comprising an operational amplifier and a voltage converter. The operational amplifier includes an inverting input, a non-inverting input, an output, a first power supply input and a second power supply input, and is configured to generate an output signal in response to an input signal. The voltage is operably coupled with the first power supply input of the operating amplifier, and is configured to receive a first supply voltage and generate a second supply voltage to the first power supply input of the operational amplifier. The voltage of the second supply voltage is relatively closer to the expected operating voltage range of the output signal than is the first supply voltage.
摘要:
A cartridge for simultaneously dispensing at least two different materials includes an elongated hollow housing having at least one partition extending laterally and longitudinally thereof to provide at least two chambers for holding the respective materials. A plunger sliding within the housing severs or slits the partition so that it can be stored during operation outside of the respective chambers. The partition may be coiled up or it may be directed laterally around the plunger so that it is stored adjacent an internal wall of the housing.
