I have an MCP601 op-amp and a piezo disc and I want to amplify the signal from the piezo but also have a biased signal in order to read the negative voltages. The device is supposed to be used as a guitar tuner to pick up the vibration of a string.
Can someone explain how I would get this effect, I have read http://www.allaboutcircuits.com/textbook/semiconductors/chpt-8/op-amp-practical-considerations/ but I don't really understand it.
