Complex sentence: Although the power supplies are not shown in the operational amplifier designs below, they can be critical in operational amplifier ds (e.g., power signal ripple, non-zero source impedance) may lead to noticeable deviations from ideal operational amplifier behavior.
Split into simpler sentences: Although the power supplies are not shown in the operational amplifier designs below, they can be critical in operational amplifier design. Power supply imperfections (e.g., power signal ripple, non-zero source impedance) may lead to noticeable deviations from ideal operational amplifier behavior.
