I want to amplify a signal within 0-50mVp-p and with the frequency range between 10KHz to 15MHz (or 10MHz).
first I have used two unity buffer to measure the signal (is similar to instrument Amp)
But when I simulated the circuit, AD8129 doesn't have a linear gain in the band of 10KHz to 10MHz. you can see the gain=Vout/Vin is not linear in the below pic:
so I decided to compensate the RF and RG (I mean feedback resistors) of AD8129 with some capacitors to have a linear gain like this article:
Adjustable Cable Equalizer Combines Wideband Differential Receiver with Analog Switches | Analog Devices
can you help me to design to have a maximum gain linearity with AD8129? (it's very important to me bcoz I have a medical application)
it's my email: email@example.com
