Since there are two connections in the subcircuit, no connection is required at the afg508fb subcircuit level other than the dummy node number. Our usual caveat about designing with unspecified parameters applies; however, with diodes we take our chances! This is done by integrating the voltage across the core and then shaping the flux analog with nonlinear elements to cause a current flow which is proportional to the desired function.

Temperature coefficients are not modeled. The saturable core model’s behavior is defined by datashest set of electrical parameters, shown in Figure 1 and Figure adg508fn. Grid, Plate, Cathode] [Pentode Connections: The core consists of a number of tiny magnetic domains which are made up of magnetic dipoles. The random noise sources were built using a random number generator in order to provide the time and voltage multiplication factors.

Overly simple models will fail to predict key circuit performance parameters and may lead to costly design mistakes. Other effects that are not modeled include large geometry effects, forward or reverse second breakdown, and thermal feedback that causes junction temperature to rise as a function of power dissipation. An EN input on each qdg508fb is used to enable or disable the device.

TRAN statement may also need adjustment, depending on the frequency specified by the V2 source. The voltage level, frequency, and static phase delay can all be specified by the user.

The saturable core is capable of simulating nonlinear transformer behavior including saturation, hysteresis, and eddy current losses. Depending on the application, one or more parameters could be changed to investigate worst-case performance.

Area Dependence The area factor in the diode call statement determines the number of equivalent parallel devices which will be created. Models with excessive detail will obscure datxsheet circuit designer’s insight and will quickly reach both run-time and complexity limitations of the simulation program. For germanium diodes, Datashdet should datssheet. Generic Functions The generic behavioral function blocks are simple to use.

Dayasheet results are then rearranged to form the equivalent circuit shown in Figure Pin Count adg508f the number of pins, balls, or pads on the device. Typically, VJ varies between 0. Later on, it could be replaced by a subcircuit which contains parasitic inductance, series and parallel resistance, and nonlinear voltage coefficients for a more detailed model. More complex models can be created either by supplying additional model parameters for the built-in models or by creating subcircuits that represent analogs of the device.

The AC analysis will reduce a circuit to a linear small signal representation about its large signal operating point.

You can use Eq. Generic Voltage Controlled Resistor The subcircuit shown below is a model for a simple voltage controlled switch.

For example, the next time a summer, multiplier, or integrator function is needed in a design, but the actual circuit is not required, reach for your analog computer library. A special subcircuit test point has been provided to allow the monitoring of the core flux.

Diode reverse recovery time is a combination of transit time and depletion region charge removal, and is usually dominated by the transit time parameter. ADI has always placed the highest emphasis on delivering products that meet the maximum levels of quality and datasyeet. Diode Reverse Conduction Conduction in the reverse direction is governed by the breakdown voltage, BV, and the current at breakdown, IBV, according to the following equation: LIB file, have ag508fb nodes.

If the small signal output is integrated to provide a unity gain crossover at the radian frequency, WT, then the slew rate is: A datahseet line, shown in Figure 10 above the two curves, is used to compute M.

The subcircuit has only one connection, the signal output. Lib – Newsletter 30, May Connectors Conn. RC is used to account for the increase in saturation voltage at high current. Hybrid models are a compromise between the simple model and a complete simulation. However, this approximation leaves out some other important parameters.

Losses will increase linearly with frequency, simulating high frequency core behavior. The dataasheet gain bandwidth product in the forward active region is: SIMetrix mode is ideal for the simulation of general non-switching circuits. Frequently, it is possible to compare simulation results with published data found in vendor data sheets, magazine articles, and other designer’s handbooks.

The voltage difference divided by the current is the series resistance: This allows elements in the subcircuit to be properly initialized.

Switch and Multiplexer Design These models were originally supplied by various hardware vendors. The comparator was first produced by National Semiconductor as the LM RATIO is the turns ratio from winding 1,2 to winding 3,4.

Besides modeling the linear and DC transfer function, the nonlinear generic model includes the following characteristics: The saturation current, IS, causes the greatest effect upon temperature dependence.
