Design and Simulation
The design of analogue circuits starts with a schematic, which is used for various time and frequency domain simulations and optimizations. Passive layout structures such as transmission lines and inductors have to be simulated using 2.5D and 3D electro-magnetic simulations. For very high frequencies even the small interconnects have to be simulated. An optimized schematic is used for the layout design, which transfers the schematic to the production technology. Once more these layouts have to be simulated and in turn may have to be optimized leading – an iterative process of schematic and layout changes till the final design.
Chip performance can be optimized for various parameters such as frequency range, output power, noise level, chip size, power consumption, temperature range. These parameters cannot be simultaneously optimized. Our goal is to find an optimal trade-off for the given application with you.
Real World Tests
Simulated and measured chip performance usually shows some difference and a redesign of the chip may be necessary. Designer experience is the crucial factor here – not just for proper design and simulation but also for foreseeing the difference between the simulated and expected measured performance. Our design team can provide this knowledge avoiding unnecessary iterations.
Typical Parameters for MMIC Optimization:
- Frequency range
- Output power
- Noise level
- Chip size
- Power consumption
- Temperature range
