An operational amplifier and a method for amplifying a signal. Embodiments provide a convenient and effective mechanism for reducing die area, design time and design verification time by sharing compensation components between the common-mode and differential feedback networks of the operational amplifier. As such, fewer compensation components are required, thereby reducing component die area. Additionally, given that the compensation components are shared between the common-mode and differential feedback networks, the feedback networks can be stabilized together with fewer compensation components to specify and verify, thereby reducing design and design verification time. Further, embodiments provide a compensation component coupling which does not couple directly to virtual ground, thereby reducing the noise of the operational amplifier.
