Web15 de fev. de 2024 · Yes and no. The opamp would generally have better PSRR, a plain follower rarely makes it beyond about 50 dB. Mind you, it is easy to nullify that advantage if you proceed to use rail decoupling capacitors to pump power supply noise into a highish-impedance shared ground return. Some RC filtering can work wonders. Web1 de jun. de 2024 · A simple zero gain buffer is a matter of an opamp and just a few components and a way of powering them, so that will be my first goal in designing a circuit and pcb layout.
