In this article I will hand to you how to sweep resistance in LTSpice with step by step tutorials. Unlike voltage and current, resistance sweeping is not possible to do in the DC Sweep section under Edit Simulation Command. The convenient way to sweep resistance is through the spice directive. The same process on how to setup a voltage sweep

This article will uncover the fixed bias configuration with a divider resistor complete analysis. Actually this is another variation of a fixed bias circuit as shown in Figure 87. The only difference of this circuit is the addition of a resistor RB2 as shown in the figure. At application wherein the base is not tied up with the supply , when

This article will uncover the complete analysis of a fixed bias circuit. Figure 73 below shows a simple common emitter configuration. It has a base resistor RB, collector resistor RC but no emitter resistor. In general, this biasing technique is called as non-emitter stabilized bias because there is no emitter resistor. By some, this is also called as the fixed bias.

There are several ways on how to sweep current in LTSpice. You can do it through DC sweep command tab, using the step command or through the list command in the spice directive. For first timer in LTSpice, click this beginner’s tutorial. In this tutorial I assume that you have already basic knowledge on LTSpice so I jump directly to

In this article we are going to explore the ways on how to sweep voltage in LTSpice. Personally I like LTSpice, aside from being a freeware, it is easy to use. It really does what paid simulation software can do (although not that fast when dealing with analog simulation such as switching power supply). For beginners guide, click />this. There

One of the easiest methods to tune a controller is through automatic tuning. This is the principle of control tuning using Simulink auto tune feature. Unlike root locus tuning in Matlab, control tuning using Simulink auto tune feature is very easy to do and can be done in a short duration only. However, you still need to know the plant

This design reference is for 7V to 25V input with 5V and 1.5A output buck converter using LT1376-5 controller. LT1376-5 is monolithic buck mode switching regulator which has a fixed frequency of 500 kHz. The switching element is internal on the controller thus lower component count. The internal switch can able to handle 1.5A current. The controller can be used with

Is it worth investing for power supply with low standby power? Come; go with me to explore the answer of this question. Nowadays power supply technology is advancing. There are so many features added that may or may not be useful for end users. It is important for the end users to define his requirements so that to get the

There are few methods to do control tuning in Matlab. One of these is control tuning using root locus editor in Matlab SISO feature. Unlike control tuning using Simulink which is automated, control tuning using root locus editor in Matlab is a manual tuning. On below figure, the upper left box is the root locus editor where you tune your

Will my electric bill decrease when I unplug appliances not in use? This is the question of many people perhaps. Let us find out if there is really a savings from unplugging devices not in use. Many of us rely only in the remote control to put our appliances in sleep mode or standby mode but not totally cutting the power
