What ProMOST can do

Features & capabilities

ProMOST is designed around one principle: give circuit designers the fastest possible path from transistor specification to optimized device — with full model accuracy and no waiting.

Core capabilities

Built for speed and accuracy

Every feature in ProMOST is tuned for the analog and RF designer's workflow. Results update in real time after any input change.

⚡
Real-time calculation

ProMOST has no "Run" button. After entering or changing any input value, calculations and sweeps execute directly — almost without delay.

📐
Dimensioning & optimization

Calculate bias settings and device dimensions in such a way that transistor performance is tuned or optimized for each individual transistor in your schematic.

〰️
Constrained sweeps

Sweep bias settings, component values, or environment parameters — constrained (constant Ids, gm, …) or unconstrained — to enable full optimization.

📡
AC & RF properties

Loaded y-parameters, s-parameters, noise, mismatch, OIP, IIP, harmonic content and more — through the main GUI and add-in panels.

🧩
Compound models

Full support for transistors extended with diodes, passives, and juncaps. Both per-device and equivalent OP parameters are listed for the complete model.

🔄
TheConverter

Convert Spectre or (H)SPICE process data (scs, lib files) to ProMOST technology files — once per PDK release, using convenient recipe files.

Operating point data

Extended OP overview

ProMOST outputs a comprehensive operating point report for every configuration. For compound models, both the per-device OP data and the equivalent OP parameters of the complete model are listed.

ProMOST calculation flow ProMOST compound model flow
ProMOST's calculation flow: from technology data and bias settings to graphical and numerical output. For compound models, background solvers and kernels are employed.
Add-in panels

Extended calculation add-ins

ProMOST ships with add-ins that expose more in-depth or more advanced sweeps, letting designers optimize for specialized properties.

Distortion add-in: IP2 and IP3
The distortion add-in: IP2 and IP3 for a constrained sweep at 900 MHz. Provides data on distortion and non-linearities for circuit optimization.
Switched-as add-in: impedance and capacitance
The switched-as add-in: equivalent impedance and capacitance of a decap-switched MOS transistor as function of frequency, using a lumped equivalent model.
Supported models

Transistor models

ProMOST includes a comprehensive library of industry-standard transistor models, updated with each release. Compound models — consisting of at least one transistor with diodes, juncaps, and passives — are also supported.
