Zagreb, Croatia - January 27, 2012 - Systemcom Ltd announces silicon validated Current-Input Analogue Front End IP module, designed like sensor signal interface, primarily intended for processing current given by the sensor at the input of electronic system.
Interfacing numerous sensors with current outputs in various industrial and consumer applications is made easy applying this IP module. The excellent features make this IP module the ideal solution for interfacing optical sensors as a phenomenon detector in biomedical applications, for example in blood-oximeters. It is also very applicable to a broad range of chemical sensors (oxygen sensor, CO sensor, etc.) used for example in environment-quality monitoring.
The current input for the IP module is solved by the original transimpendance amplifier (TIA) architecture with unique offset cancelling solution, giving very good linearity and fast current to voltage conversion. Wide range of conversion ratios together with programmable gain amplifier (PGA) enables measurement of low input absolute current values in the range of hundreds of picoA to 1 mA and measurement of relative current down to the level of tens of picoA. The integrated S&H circuit with fully differential output makes it convenient for implementation into SoC system and further signals processing.
The module operates at supply voltages from 1.6 V to 1.8 V in temperature range from -40°C to 125°C. The IP module is silicon validated in TSMC 180 nm mixed signal CMOS technology.
