In this book, PSpice for Filters and Transmission Lines, we examine a range of active and passive filters where each design is simulated using the latest Cadence Orcad V10.5 PSpice capture software. These filters cannot match the very high order digital signal processing (DSP) filters considered in PSpice for Digital Signal Processing, but nevertheless these filters have many uses. The active f...

The Interactive Command Language (ICL) significantly extends the simulation performance of several programs based on SPICE3 standard for the analysis of electrical networks in the so-called sequential mode, when the relatively independent tasks are run consecutively with a possibility of data exchange. However, the ICL is not implemented in the well-known OrCAD PSpice simulation program. The pa...

This paper provides an Analog Behavioral Model (ABM) in PSpice of a tunnel diode The PSpice parameters are implemented as separate parameterized blocks constructed from SPICE (ABM) controlled sources and extracted through experiment. A tunnel diode based oscillator is also proposed and simulated using circuit analysis software. The behavior of the tunnel diode is simulated and compared to the m...

PSPICE modeling of a commercial LED driver IC (TOP245P) and PC817A optocoupler is proposed for the switch-mode power supply (SMPS) (applicable to LED driver) design and simulation. An analog behavioral model of the TOP245P IC including the shunt regulator, undervoltage(UV) detection, over-voltage(OV) shut-down and SR flip-flop is developed by using PSPICE. The empirical equation of PC817A curre...

In PSpice for Analog Communications Engineering we simulate the difficult principles of analog modulation using the superb free simulation software Cadence Orcad PSpice V10.5. While use is made of analog behavioral model parts (ABM), we use actual circuitry in most of the simulation circuits. For example, we use the 4-quadrant multiplier IC AD633 as a modulator and import real speech as the mod...

This paper investigates on the propagation in a coaxial cable with the assumption that the distributed parameters are variable with the longitudinal distance from the source due to a linear temperature variation. This work addresses the problem of propagation in borehole conditions where the temperature varies by approximately 3°C/100m. In addition to the temperature variation along the coax we...

ID#413 – Author: Sreeram Rajagopalan 2 1. ABSTRACT PSpice A/D is a simulation package that is used to analyze and predict the performance of analog and mixed signal circuits. It is very popular especially among Printed Circuit Board (PCB) engineers to verify board level designs. However, PSpice A/D currently lacks the ability to simulate analog components connected to digital circuits that are ...

This paper presents a complete behavioral PSpice model for IGBT transistor. A voltage dependent capacitance is modeled using a second order polynomial and “arctan” function. The simulation results for I-V static and transfer characteristics and their comparisons with datasheets are shown. The dynamic model verification is carried out using PSpice simulations and experimental measurements of the...

Navy shipboard power systems have different characteristics when compared to utility power systems. To conduct system studies on shipboard power systems, an effective simulation tool is required to model shipboard electric power systems. PSpice is a very powerful tool for analog/digital circuit simulation, but it is rarely used for power systems. This paper presents modeling shipboard power sys...
