Chapter 5Transimpedance Amplifier Specifications
In this chapter we examine the main specifications of the TIA: the transimpedance, the input overload current, the maximum input current for linear operation, the bandwidth, the phase linearity, the group-delay variation, the jitter, the input-referred noise current, and the crosstalk (for multichannel TIAs). We discuss the measurement of the transimpedance and the noise and calculate the power penalty due to crosstalk. We conclude with a table showing the data of commercial parts for illustration.
5.1 Transimpedance
Definition
Figure 5.1 defines the input current 
and the output voltage 
of single-ended and differential TIAs. Note that in the differential cases, Figs 5.1(b) and (c), 
is defined as the voltage difference 
and 
is defined as the current difference 
. All output voltages are defined under terminated conditions, that is, a ...
