Abstract: PURPOSE:To ensure simple improvement for the ripple without using any large- capacity electrolytic capacitor by applying the ripple component nearly equal to the ripple component given from the power source leaking to the non-reverse input end to the reverse input of the amplifier. CONSTITUTION:The input signal is applied to non-reverse input end (+) of amplifier A2 from input end IN, and at the same time the fixed voltage is applied to the input end from power source VCC via bias circuit B2. On the other hand, the fixed feedback signal is applied to reverse input end (-) of A2 from output end OUT via feedback circuit NFB along with the cancel voltage applied from VCC via cancel circuit CAN. In such constitution, ripple voltage V2 emerging at the OUT can be expressed by the equation (where G2 is the gain of A1, and v1 and v2 are the ripple components emerging at (+) or (-) of A2 via B2 or CAN). Accordingly, v1=v2 is secured for each ripple component with the same phase, and as a result V2 is turned zero to improve the effect of the power ripple.
