1-Tone Nonlinear Sim - Spect, Gain, Harmonic Distortion vs. Frequency (with PAE)

1-Tone Nonlinear Simulations > Spectrum, Gain, Harmonic Distortion vs. Frequency (w/PAE)

Description

This simulation setup is identical to the HB1ToneFswp schematic, except that it includes two current probes and named voltage nodes for calculating power-added efficiency. It also simulates the spectrum, voltage waveform, output power, power gain, high supply current, DC power consumption, thermal dissipation, and harmonic distortion, of a device or amplifier, all versus frequency. A sample power amplifier is provided. You must replace this amplifier with your own device or amplifier, and you can modify the biases, as described in the notes, below.

Needed to Use Schematic

A device or an amplifier using nonlinear model(s)

Main Schematic Settings

Bias settings, input frequency sweep range and available source power

Data Display Outputs

All versus frequency:

Output spectrum, at a frequency selected by moving a marker
Output power
Transducer power gain (power delivered to the load minus power available from the source)
Harmonic distortion up to the 5th, in dBc
Power-added efficiency (Pout at fundamental minus Available source power)/(DC power consumption)
High supply current
DC power consumption
Thermal power dissipation in the device or amplifier

Schematic Name

HB1TonePAE_Fswp

Data Display Name

Note

Only bias supplies on the highest level schematic will be included in the PAE calculation. For example, if you replace the sample amplifier with one with the bias supplies included in the subcircuit, those supplies will not be included in the PAE calculation. On the highest level schematic, you can delete one of the two supplies and/or replace the voltage sources with current sources, and the PAE calculation will still be valid. You can modify the components in the bias network, realizing that the DC power consumption is computed as (the DC voltage at the Vs_high node) * (the DC current in the Is_high current probe) + (the DC voltage at the Vs_low node) * (the DC current in the Is_low current probe).
