Figure 52. Photodiode Preamp Frequency Response
The pole in the loop transmission translates to a zero in the
noise gain of the amplifier, leading to an amplification of the
input voltage noise over frequency.
The loop transmission zero introduced by CF limits the
amplification. The noise gain bandwidth extends past the pre-
amp signal bandwidth and is eventually rolled off by the decreasing
loop gain of the amplifier. The current equivalent noise from the
inverting terminal is typically negligible for most applications.
The innovative architecture used in the ADA4817-1/ADA4817-2
makes balancing both inputs unnecessary, as opposed to traditional
FET input amplifiers. Therefore, minimizing the impedance
seen from the noninverting terminal to ground at all frequencies
is critical for optimal noise performance.
Integrating the square of the output voltage noise spectral density
over frequency and then taking the square root allows users
to obtain the total rms output noise of the preamp. Table 9
summarizes approximations for the amplifier and feedback
and source resistances. Noise components for an example
preamp with RF = 50 k, CS = 30 pF, and CF = 0.5 pF
(bandwidth of about 6.4 MHz) are also listed.
