Low Noise Broadband Amplifier for Breast Cancer System
2022 35th SBC/SBMicro/IEEE/ACM Symposium on Integrated Circuits and Systems Design (SBCCI)(2022)
Abstract
This work proposes to develop a Low Noise Broadband Amplifier in CMOS 180nm tecnology, with supply voltage of 1.8V. The circuit has three stages, the first a common gate amplifier, followed by a common source amplifier, finally a buffer to assist in the measurement. It achieves a noise figure slightly higher than 6.3dB, an area of 0.17mm2 without the pad-ring, consumption of 7.3mW, a band above 10dB from 2.5GHz to 8.1GHz, the gain varies between 10 to 16.9dB, and port isolation is less than -10dB for the entire range. The block is an integral part of a breast cancer system receiver, but finds other applications in IoT and healthcare industries.
