LTC6240 Low Noise 1M Trans-Impedance Amplifier
Jan 10th 2007
By using a 10Megaohm resistor, with a noise of 400nV/rtHz, for transimpedance gain and then attenuating the signal by 10 results in an equivalent gain of 1Megaohm with only 40nV/rtHz of noise. This is less than 1/3 the noise of a single stage TIA with a 1Megaohm resistor. ...

The control voltage, Vin, is converted to a charge on a capacitor that is referenced to ground. This charge is transferred to place a differential voltage across the output current programming resistor. The output current then flows into a ground referenced load for a precision single supply circuit without the need for a voltage ...

Large area photodiodes come with a large capacitance, typically on the order of 3000pF or larger. This capacitance to ground at the input of a transimpedance amplifier has a significant effect on the output noise of the circuit as the noise gain increases dramatically at higher frequencies. AC coupling a bootstrap JFET across ...
Small Area Photodiode in Normal TIA Configuration
Aug 22nd 2006
Small area photodiodes have low capacitance. To maintain low noise operation it is important to keep the input capacitance low so that the miniscule input noise current of the CMOS amplifier, and not the voltage noise, dominates the overall circuit noise. The total input capacitance from the amplifier in this circuit is the ...
