I'm designing a portable biological signal acquisition system for my licence project and while designing the mixed signal board, a potential problem came in my mind: is it stable ?
I'm using an opamp (OPA350) as a buffer for the reference voltage (I'm using the reference voltage as a virtual ground). For every instrumentation amplifier I connected a capacitor between 5V (the positive supply rail) and reference, and one between analog ground (the negative supply rail with respect to the virtual ground). Is this circuit prone to oscillation because of these capacitors ?
Thanks !
