Abstract

Current mode signal processing has some advantages over voltage mode signal processing in low
voltage and low power applications because of not requiring high precision resistors or capacitors.
And one reason to be chosen current mode signal processing is many signal sources are current-type,
such as temperature sensors, photo sensors and many others in biomedical. This study reports
development and simulation of two types of Analog/Digital Converters (ADCs)for low-power and
small area applications, such as implantable telemetric biomedical recording applications. In
development of these analog-to-digital (AD) converters current mode signal processing is chosen.

Keywords

Analog-digital converter, Current mode approach, Current mirror, Current multiplication
