| Zusammenfassung: | A technique is provided for acquiring data with reduced correlated low frequency noise interference via a data acquisition circuit. The data acquisition circuit includes a plurality of data channels comprising a plurality of amplifiers and a biasing circuit for providing bias voltages to the plurality of amplifiers. The biasing circuit is configured to generate the bias voltages and establish a relationship between the bias voltages so as to reduce correlated low frequency noise in the plurality of amplifiers. |
