Abstract
An amplifier comprising a gain stage with a feedback network comprising two ports between which at least three capacitors are connected in series and between each pair of capacitors a resistor is connected to a predetermined voltage. The gain stage is provided in a feedback loop over a primary amplifier.
Claims13
An amplifier comprising:
- a compensator having:
- a network comprising two ports between which at least three capacitors are connected in series and between each pair of capacitors a resistor is connected to a predetermined voltage, and
- a gain stage having:
- an gain stage input, connected to one port and
- an gain stage output connected to the other port,
- a primary amplifier having:
- a primary amplifier output operatively connected to the gain stage input and
- a primary amplifier input operatively connected to the gain stage output and
- a feedback filter being a high pass filter provided between the primary amplifier output and the primary amplifier input.
