摘要： The present invention relates to a signal conditioning circuit, comprising: an amplification and filtering chain (5C) having amplifier means (6) and filter means (7), each with an input connection (6A, 7A) and an output connection (6B, 7B); a first feedback path (8) for providing feedback to said amplification and filtering network (6, 7), including a first phase-shifting network (11) having an input connection (HA) and an output connection (11B). The circuit (5) is characterized in that it comprises a second feedback path (9) for providing feedback to said amplifier means (6), including a second phase-shifting network (10) having an input connection (10A) and an output connection (10B); said input connection (11A) of said first phase-shifting network (11) being connected with said output connection (6B) of said amplifier means (6); said output connection (HB) of said first phase-shifting network (11) being connected with the input connection (10A) of said second phase-shifting network (10) and with said input connection (7A) of the filter means (7); said first phase-shifting network (11) being designed to compensate for errors in said output connection (6B) of said amplifier means (6) or to operate when said output connection (6B) of said amplifier means (6) is in a saturated condition.
