Abstract: The development of a low power, Low Noise Amplifier ( LNA) and Digital to Analog converter ( DAC) for integration into a Closed-loop Deep Brain Neuro-Simulator( CDBS) represents a critical step in advancing the field of neural interface technology. This report outlines the systematic design and implementation process of these vital analog and mixed-signal components using Cadence Virtuoso. The design encompasses circuit architecture selection, schematic design, noise analysis, low power optimization, layout design, simulation, verification, and post-layout considerations.
The report emphasizes the significance of achieving low power consumption and minimal noise while meeting strict performance requirements. The final LNA and DAC designs are subjected to comprehensive testing and integrated into the CDBS, ensuring their seamless operation within the closed-loop neuro simulation system. The result not only showcases the capabilities of analog and mixed-signal design but also highlights the essential role these components play in enabling precise, real-time neural interfacing and control in neuroscience research and therapeutic applications.
Keywords: Low Power, Neuro-stimulation, Closed-loop, Analog and mixed-signal design.
