Construction of a Low-Noise Amplifier Chain With Programmable Gain and Offset
A low-noise, variable gain amplier chain was constructed for interfa-cing a sensor to an ADC. During the course of the work two dierent methods -switched-capacitor circuits and chopping circuits - for dealing with 1/f noise wereinvestigated during the course of the work. The resulting circuit did no...

| Summary: | A low-noise, variable gain amplier chain was constructed for interfa-cing a sensor to an ADC. During the course of the work two dierent methods -switched-capacitor circuits and chopping circuits - for dealing with 1/f noise wereinvestigated during the course of the work. The resulting circuit did not quitemeet the performance required by the specication, some possible improvementsare suggested. |
