| Zusammenfassung: | The inventive level shifting circuit shifts an analog input signal by a precise amount. This allows it to be used in precision instrumentation applications where precise signal shifts are critical. It uses a self-biasing feedback circuit to determine the bias current needed to shift an analog signal by a desired amount. The circuit automatically compensates for influences by temperature, supply voltage, and process variations. This circuit also has value as a stand-alone function for other (non-programmable) products. |
