tailieunhanh - A low power, low noise chopper instrumentation amplifier using body control DC servo loop and low input capacitance

This paper presents a proposed low power, low noise capacitively-coupled chopper instrumentation amplifier (CCIA) using body control DC servo loop and low input capacitance applied for biomedical recording. A DC servo loop using body control (DSL-BC) is proposed to reduce the electrode offset and its noise contribution. |
