The following section summarizes the steps in a typical simulation. The rise, fall, and delay measurement mode computes the time, voltage, or frequency between a trigger value and a target value.
Examples for transient analysis include risefall time, propagation delay, and slew rate measurement. B. Use Hspice to plot an amplifiers openloop frequency response and be able to measure low frequency gain, gain bandwidth product, phase margin, and gain margin. C. Use Hspice to plot the closedloop transient response of an amplifier, and be able to plot and measure both the largesignal (e. g. slewrate) and smallsignal (e. g.

HSPICE Once you have completed and saved your deck, you can compile it using the following command from the UNIX prompt: myth0: hspice tutorial. sp! tutorial. lis& This will run the HSPICE compiler and pipe the resulting output file into the file named tutorial. lis. It is suggested that you use the same name for the. sp and. lis files.

Paul Hasler, Advisor Figure 12 Test circuit with variable input slew rate The slew rate is the rate at which the voltage is allowed to change and is measured in Vsec. The slew rate is different for each generation of op amps The measurement in dB will allow us to create a graph of the gain vs.
frequency. 5. Change the amplifier to a gain of 20 and repeat steps 2 4. 6. Setup the amplifier with unity gain. 7 Measurement.
The slew rate can be measured using a function generator (usually square wave) and an oscilloscope. The slew rate is the same, regardless of whether feedback is considered. Slew rate limiting in amplifiers. There are slight differences between different amplifier designs in how the slewing phenomenon occurs. Slew rate: the time for the input signal going from 10vdd to 90vdd.
Measure the I avg for one or N cycle time NOTE: the simulator can also be set to Hspice for which you need choose HspiceD as your simulator and the model path is
