Using a ladder network is a common way of creating an 8 bit DAC (Digital to Analogue Converter) as each control bit contributes to a binary weighted output voltage. However, for a highly accurate DAC, the resistors will be laser trimmed and located inside a chip. A Binary Ladder Circuits is constructed of resistors having only two values and thus overcomes the disadvantages of weighted resistors. The left end of the ladder is terminated in 2 R, as shown in Fig. 17.14. An enhancement of the binary-weighted resistor DAC is the R-2R ladder network. This type of DAC utilizes Thevenin's theorem in arriving at the desired output voltages. The R-2R ... By constructing a different kind of resistor network on the input of our summing circuit, we can achieve the same kind of binary weighting with only two kinds of.

An actual ladder diagram of a relay-based motor control system is shown here, complete with red-line edits showing modifications to the circuit made by an industrial electrician: Perhaps the most confusing aspect of relay control circuits for students to grasp is the meaning of normal as it applies to the status of relay contacts. As discussed ....

LC Ladder. This circuit is a simple model of a transmission line. A pulse propagates down the length of the ladder like a wave. The resistor at the end has a value equal to the characteristic impedance of the ladder (determined by the ratio of L to C), which causes the wave to be absorbed. A larger resistance or an open circuit will cause the. R-2R ladder systems give a straightforward intends to change over digital data to an analog yield. The performance of the R-2R DAC in terms of efficiency or resolution is the major issue of this type of network Due to mismatching of resistor the performance of R-2R is somehow limited although this type of ladder can be realized as a ICs.

L Matching Network Calculator. The following is a design tool which calculates the values for an L matching network. The Q (bandwidth) of a filter is fixed for an L matching network, because it is set by the ratio of the source and load resistance which are typically fixed values. For a variable Q use a Pi or T matching network. This calculator. When the source network has a ladder structure and contains no controlled (dependent) sources, R TH is easily found by series-parallel reduction of the dead network.

A resistor ladder is an electrical circuit made of repeating units of resistors. Two configurations are discussed below, a string resistor ladder and a R-2R. Voltage Ladder. A voltage ladder is a circuit that consists of several resistors in series with a voltage placed across the entire resistor network. Each resistor in the network has a higher voltage drop than the one before it. Since the resistors in the ladder are in series, the current is the same all throughout.
