- William M Connelly added an answer:Does anyone have knowledge on Grass Instruments Model P16 Micro Electrode DC Amplifer?
Does anybody has the manual for Grass Instruments Model P16 Micro Electrode DC Amplifer?. It would be possible to use it for extracellular recording?
I don't have a manual, but I would certainly think it could perform field or EEG recording. Just keep the capacitance compensation off (or very low)Following
- Sujit K. Biswas added an answer:What is the virtual ground in an op-amp in a open loop configuration and in feedback configuration?With diagram if possible.Ground in an electronic circuit refers to the common reference point for power supply and signals. In an open loop op-amp circuit, there is no concept of 'virtual ground'. However, in an op-amp with negative feedback such that it behaves as an amplifier, the inverting input maintains exact potential as that of the non-inverting input. Now, if the non-inverting input is physically connected to ground (as is done in most cases), the inverting input is said to be at 'virtual ground' since it has the same potential as ground without being physically connected to the ground.Following
- Robert John Taylor asked a question:Does anyone have a practical amplifier circuit diagram for use with an InGaAs avalanche diode? - Free Space Optical linkWe are thinking of using a Hamamatsu G8931 - 20 avalanche diode and a transimpedance amplifier such as the MC2007-3. Any suggestions?Following
