Generador

Triangle Wave Generator
This circuit implements a triangle wave generator using two op-amps. The first op-amp acts as an integrator. The second op-amp acts as a non-inverting amplifier, with itsoutput voltage limited to approximately plus or minus ten volts by the two zener diodes. The Sine Wave block modulates the waveform amplitude via the Variable Resistor block, and the DC Voltage Sourcecan be used to add a DC offset. See the Example - Modeling a Triangle Wave Generator section of the SimElectronics® User Guide for more information on how to construct this model using the Simscape™ andSimElectronics block libraries.
The two Band-Limited Op-Amp blocks are parameterized based on an LM7301 device. The datasheet gives the gain as 97dB which is equivalent to a gain of10^(97/20)=7.080e4. Input resistance is given as 39e6 ohms, and slew rate as 1.25V per microsecond. Bandwidth is given as 4MHz. No value is given for the output resistance, so this is set to zero. In practice theoutput resistance will be small compared to output series 1000 ohm resistor in this circuit.

El generador de la Ola del triángulo
Este circuito implementa un generador de la ola del triángulo usando dos op-amp. El primer op-amp actúa como un integrador. Elsegundo op-amp actúa como un amplificador que poco invierte, con su voltaje de salida limitado para aproximadamente más o menos diez voltios por los dos diodos del zener. El bloque de Onda sinusoidalmodula la amplitud del waveform por el bloque Variable Resistor, y la CD Voltage Source puede usarse para añadir un offset de CD.
