LTspice Modeling of Universal Operational Amplifier

LTspice model with 4 levels of accuracy of the description of an operational amplifier.The first level models a linear single pole opamp with no slew rate or output voltage range limit. The second level introduces the slew rate and output voltage and current limit. The third level is a two pole with programable phase margin […]

Designing and Simulation of LNA using LTspice and Matlab

Ventspils University College Faculty of Information by Marcis Bleider LOW NOISE PREAMPLIFIER FOR SATELLITE BASE STATION   In this article low noise preamplifiers (LNA) for satellite ground station (GS) of Ventspils University College (VUC) are designed creating possibility to repair and replace these commercially expensive, extremely sensitive and easily damageable units. One of main purposes of GS of VUC is for […]

Low Noise Preamplifier for Satellite Base Station

LTspice Bias circuit simulation and PCB Eagle file of a low noise amplifier circuit (LNA ) for satellite. 3 different bias networks are compared in this simulation. Project Type: FreeComplexity: IntermediateComponents number: 11-20SPICE software: LTspiceSoftware version: IVFull software version nedeed : No

Using a Stepped PWL input file

Using a PWL file to input a waveform into a circuit is simple. But if you have to step through several waverform files, it becomes difficult to implement. This method allows LTSpice to step through each waveform input file so that the results of your simulation can be compared on the graph. Project Type: FreeComplexity: […]
