ABSTRACT:
A two stage operational amplifier circuit comprises a first stage (31) having an input (2, 4) and an output, and a second stage (33) having an input and an output (19). The second stage input is coupled to receive the first stage output. A feedback path (41, 45, 47, 51) is coupled between the output and the input of the second stage. The feedback path (41, 45, 47, 51) comprises a low-frequency compensation path (41, 45) and high-frequency compensation path (45, 47, 51). The feedback path (41, 45, 47, 51) is compensated such that the frequency response of the second output of the second stage is substantially 6 dB per octave throughout the high-frequency region.
