When designing for ultra-low power, choose system components carefully. To minimize current consumption, select large-value resistors. Any resistors react with stray capacitance in the circuit and the input capacitance of the operational amplifier (op amp). These parasitic RC combinations can affect the stability of the overall system. A feedback capacitor may be required to assure stability and limit overshoot or gain peaking.
When possible, use AC coupling and AC feedback to reduce static current draw through the feedback elements. Use film or ceramic capacitors because large electolytics may have static leakage currents in the tens to hundreds of nanoamps.
