Kick start a crystal oscillator in Spice - 05/27/99 EDN-Design
Ideas....Starting up oscillator circuits and getting them to maintain oscillation in a
Spice simulation is difficult. Some high-frequency crystal circuits require days for
the oscillation to reach steady state. Thus…PDF has several circuits, please scroll to
find this one…. [Design Idea by Adam Chen, Cypress Semiconductor, Woodinville, WA] |

Linearizing an RTD is easy with SPICE - 08/03/98 EDN-Design Ideas....A
popular way to design an accurate temperature probe using an inherently nonlinear
device--a resistance temperature detector (RTD)--uses positive multiplicative
feedback. However, the transfer function of this method is also nonlinear, making an
analytical approach difficult. A simpler method uses Spice....Multiple circuits in

Low-noise ac amplifier has
digital control of gain and bandwidth - 02/05/04 EDN-Design Ideas....In
low-noise analog circuits, a high-gain amplifier serves at the input to increase the
SNR. The input signal level determines the input-stage gain; low-level signals require
the highest gain. It is also standard practice in low-noise analog-signal processing
to make the circuit's bandwidth as narrow as possible to pass only the useful
input-signal spectrum.... [Design Idea by Philip Karantzalis, Linear Technology,
Milpitas, CA, |

Model a nonideal transformer in Spice - 06/05/00 EDN-Design
Ideas....Designers often use transformers as voltage, current, and impedance adapters.
Transformers usually comprise two inductively coupled coils, wound around a ferrite
core. The coupling between the windings is never perfect. Spice provides a
model....PDF contains several designs, scroll to find this one.... [Design Idea by

Model NTC Thermistor in SPICE - SPICE subcircuit accurately models NTC
thermistor. Model uses the .TNOM statement to set temperature. This allows
circuits with transistors and diodes to be analyzed over temperature.… [Jim Haggerman,

signals require the highest gain. It is also standard practice in low-noise
