This paper introduces a Transimpedance Amplifier (TIA) design capable of producing an incremental input resistance in the ohmic range, for signals microampere such as are encountered instrumentation electrochemical ampero-metric sensors, optical-sensing and current-mode circuits. low input-resistance is achieved using stage incorporating negative feedback. In Cadence simulation exemplary 180 nm...

The growing demand for mobile and handheld devices requires efficient low-power designs and methodologies providing acceptable levels of performance. This project studies the effects of power-management techniques, specifically clock-gating, for a general-purpose, MIPS-architecture processor. The implementation begins as a behavioral HDL model, and is converted to a synthesized model, for which...

Portable products are being used increasingly. Because these systems are battery powered, reducing power consumption is vital. In this report we give the properties of low power design and techniques to exploit them on the architecture of the system. We focus on: minimizing capacitance, avoiding unnecessary and wasteful activity, and reducing voltage and frequency. We review energy reduction te...
