Abstract :
Two methods are presented for improving the poor high-frequency response of noninverting integrators due to the limited gain-bandwidth product of operational amplifiers (o.a.s). Integrators involving two o.a.s can be upgraded by choosing the inverter´s resistance ratio in correspondence with the golden section. Furthermore, a known method for compensating Miller integrators is applied to the DeBoo integrator.
