Abstract :
The excess inductance of the conductor connecting the ground pins of the MMIC and the ground plane is extracted from a simplified procedure of measurement and optimization. The method is applied to a digital attenuator chip with a positive bias circuit. The addition of bypass capacitors with the value compensating the extracted excess inductance of the conductor clearly improves the performance of the chip.
