S3245A Noise Amplifier
The S3245A Noise Amplifier is specifically designed for high performance /high accuracy flicker noise measurements in package or on wafer. The noise amplifier can be used in conjunction with Simucad’s UTMOST III automatic parameter extraction software or stand alone for manual and interactive flicker noise measurements.
The advanced design of the S3245A amplifier meets the requirements for low amplitude noise measurements by providing constant gain for frequencies up to 300kHz. The S3245A noise amplification system allows users to provide automatic DC biasing for noise measurements.
