Postprocessing Converts Spice to RF Analyzer -  EDN-Design ideas -- 10/15/12    Designers of RF and high-frequency products need a simulator that can predict noise figure at a given frequency, minimum noise figure, optimum reflection coefficient for noise, and noise resistance. __ Circuit Design by Mojy C Chian, Harris Semiconductor, Melbourne, FL

Potentiometer Model -  (spice design)  __ Designed by Rick 

Power Supply Bypassing -  its easy to take for granted.  We place the power and ground symbols on a schematic page without considering how the power is delivered.  But, there's more to it than just two symbols on a schematic.  The figure above shows the real story of every circuit and its power source.  Understanding the nature of power leads (or traces) is key to good circuit design__ 

Precision Half-Wave Rectifier -  (spice design)  __ Designed by Rick 

Programmable Gain Amplifier (PGA) Op Amp -  The task at hand seems straightforward: read all of the system's sensors, thermistors, strain gauges, photodiodes, using a 12-bit ADC.  But getting the most from an ADC means scaling the maximum signal from each sensor to match the maximum input of the ADC.  How do you achieve this from sensors of vastly different signal strengths? One indispensable circuit is the PGA, Programmable Gain Amplifier (spice design) __ 

Protects FPGAS from Killer Spikes -  04/23/98 EDN Design Ideas:  A project using Xilinx FPGAs brought an interesting problem to light.  When you turn on the board, one FPGA in three succumbs to this problem.  A lot of frustration and testing uncovered a negative-going spike (Figure 1) in the 5V li __ Circuit Design by Nelson Nguyen, Anritsu Corp, Morgan Hill, CA

Pspice Models Nickel-Metal-Hydride Cell -  02/02/95 EDN Design Ideas:  The nickel-metal-hydride (NiMH
) battery model in Listing 1 accurately predicts the discharge characteristics of an NiMH
cell (or groups of cells).  The model accounts for: ampere-hour (Ahr) capacity of the cell; cell resistance;  differing cell capacity, depending on low- and high-rate discharge characteristics.   The basic cell model is accurate for 0.001 to 5C discharge rates, where the 1C rate is a battery-industry term for the current that will discharge a cell to its cutoff voltage (usually 1.1V) in exactly one hour. __ Circuit Design by Steve Hageman

PSpice tunes oscillators -  10/09/97 EDN Design Ideas:  A previous Design idea (Reference 1] proposes a simple technique to extend the frequency range of a tungsten-lamp-stabilized crystal oscillator (Figure 1).  The idea involves taking into account a simplified first-order expression for the frequency-dependent gain of the op amp.  After some __ Circuit Design by Lutz von Wangenheim, Department of Electrical Engineering, Hochschule Bremen, Germany

PSpice used for Thevenin equivalents -  04/23/09  EDN Design Ideas:  A simple method lets you obtain the Thevenin voltage and resistance and the Norton equivalence with the aid of simulation __ Circuit Design by David Karpaty Analog Devices Inc, Wilmington, MA

Pulse Width Modulation -  (spice design)  __ Designed by Rick 

Push-Pull Output Stage -  (spice design)  __ Designed by Rick 

Quasistatic Spice Model Targets Ceramic Capacitors with Y5V Dielectric -  08/24/12  EDN Design Ideas:  Run more accurate Spice simulations by accounting for the capacitance variation versus applied voltage.  Ceramic Y5V SMT capacitors have recently become available in values and sizes that were previously available only with electrolytic capacitors.  At first glance, they may seem a worthwhile unpolarized alternative to electrolytic capacitors, and they sometimes are.  These capacitors, however, have a capacitance that is a function of the applied voltage.   __ Circuit Design by Hugo Coolens, KaHo Sint-Lieven, Ghent, Belgium

Questions & Answers on the SPICE Macromodel Library -  AN41 Linear Technology This note provides answers to some of the more common questions concerning LTC's Macromodel Library.  Topics include hardware and software requirements, model characteristics, and limitations and interpretation of results.  __ Linear Technology/Analog Devices

RC Low-Pass Filter -  (spice design)  __ Designed by Rick 

Routine Implements Spice-3 Inductor Mode -  09/01/95 EDN Design Ideas:  in Spice-2G6 and other Spice derivatives, a dc-bias-current effect, modeled by a polynomial equation, is a part of the basic inductor model.  This equation is built into the source code, so you need only specify the coefficients of the polynomial equation.  The Spice-2G6 netlist is as follows:  L1 1 2 POLY L0L1 L2 L3   L19 __ Circuit Design by Martin O'Hara, Newport Components Ltd, Milton Keynes, UK
