Buffer Circuit
The series is a series of input buffer equal to the output. In this is such a common collector circuit of air-reinforcement = 1. R value attached to restrict the current use is issued. Great value depends on the indication of its components, is usually not installed or flow is maximized in accordance with the op-amp capability.
Buffer circuit here serves to reinforce the clock signal and synchronization for robust enough to be transmitted through a cable with a considerable distance. buffer circuit should have a fairly low output impedance. because the synchronization clock line and this is the track "bus" that is connected to a series of client (branch) in parallel. output current should also be quite large, so as to move a few branches. output buffer in addition to pulse and synchronization signals can also be used as a source of supply.
Buffer circuit using Darlington pairs that have the advantage as expected above. strengthening the buffer is quite high. R base serves as aretaining basis.Vin flow is the input voltage that comes from a series of MMV ( multivibrator). Where active at the level of ± 6V Vin = VCC.

Stabilized Capacitance Buffer Circuit Diagram
This is a simplest Stabilized Capacitance Buffer Circuit Diagram. In this simple circuit using Ql and Q2 constitute a simple, high-speed FET input buffer. Ql functions as a source follower, with the Q2 current source load setting the drain-source channel current. The LT1010 buffer provides output drive capability for cables or whatever load is required. Normally, this open-loop configuration would be quite drifty because there is no de feedback.
Stabilized Capacitance Buffer Circuit Diagram
The LTC1052 contributes this function to stabilize the circuit. It does this by comparing the filtered circuit output to a similarly filtered version of the input signal. The amplified difference between these signals is used to set Q2`s bias, and hence Ql `s channel current. Ql `s source line ensures that the gate never forward biases, and the 2000 pF capacitor at Al provides stable loop compensation.
The rc network in Al`s output prevents it from seeing high-speed edges coupled through Q2`s collector-base junction. A2`s output is also fed back to the shield around Ql`s gate lead, bootstrapping the circuit`s effective in_put capacitance down to less than 1 pF.
