Analog Integrated Circuit Optimization: A 0.22µw Bulk-Driven Telescopic OTA Optimization Using PSO Program for Low Power Biomedical Devices

Introduction

The tremendous growth in microelectronics over the past few decades have raised the CMOS technology miniaturization to a robust and an inexpensive electronic platform that is well suited for the implementation of wireless devices which they are essential parts of our everyday life. The wireless technology is used to meet the wireless devices requirements, therefore, we can move from person-to-person wireless communication towards person-to-device and device-to-device communication. Wireless technology has enabled us to obtain wearable wireless communication systems with higher speed, very small size and very low power consumption used for health monitoring system (Figure 1) (Mourad, 2018). In fact, the wearable and the implanted health monitoring technology has a strong potential to change the healthcare services future by enabling ubiquitous patients monitoring and it focuses on remote monitoring of elderly or chronically ill patients in residential environments.
