Another neat feature is the ability to switch the input impedance
from 1Mohm to 50ohm - a built-in termination to eliminate signal reflections.
10k, 25k, 50k, 100k or 600 Ohms standard input impedance
To transfer maximum power from the RF generator to the line, which is a type of distributed load, it is necessary to know the input impedance
of the line, which will optimally align the output resistance of the generator with the input impedance
The input impedance
of the designed structures is given as (Yoon, N.
A good CCI structure must provide several features: very low X input impedance
, very high Y and Z impedance, unity voltage and current gains between ports, large dynamic input and output current and voltage ranges.
Optional buffered analog input provides constant input impedance
across time and frequency and eliminates sample-and-hold kickback, simplifying input matching for passive and active analog front ends, while reducing pass band ripple.
The contributors, who are a mix of academic and industry researchers, propose novel circuit solutions for multiple-input multiple-output radio transceivers, an algorithmic design methodology for simultaneous noise and input impedance
matching in low-noise amplifiers, and a digital RF processor.
the first stage does not load the cartridge since it can be designed to have high input impedance
independent of frequency.
Fortunately, it has proven successful for PDS design to instead examine the frequency-dependent input impedance
to the power planes.
These transceivers feature extremely high input impedance
and low input current.
DUT board signal input impedance
should be kept low whenever possible.
The effective equivalent input impedance
which will be connected to the input of a second stage transfer resistance amplifier (not shown in Fig.
