I want to work with a high impedance transducer(Mega ohm order) and I was wondering about the matters that I should consider. do I need to use an opamp with special specifications? what about matching considerations?

Use charge or current amplifiers. __________________________________________________ Low-cost resistors, capacitors, and LEDs: **broken link removed**
