Investigation of Key Parameters Affecting Current Consumption in CMOS Based Design and Processor Power Consumption Saving Features for Portable Two-Way Radio System Design

In the latest portable two-way radio design, processors have been widely used as the main 'heart' to control the whole operations of the radio during idle, Receiving (Rx) and Transmit (Tx) modes instead of Applications Specific Integrated Circuits (ASIC). By integrating processor into the design, various powerful applications could be offered to the customers but at the cost of additional power consumptions even if the radio is at idle mode. Ultimately, processors are well known to be more power hungry compared to ASIC. This will post even greater challenge for the radio designers to meet the battery life specification, in which is an essential & critical customer requirement for communications during critical public safety or rescue missions.
