CM9011ff – UHF Passive RFID Front-End EPCGlobal Class 1 Gen 2/ISO18000-6C Compliant

Analog/RF front end

This macro-cell is an ultra low power analog/RF front-end core designed for SilTerra 0.18μm CMOS technology. It is ideal for use in passive UHF RFID integrated circuits compliant with EPCGlobal Class 1 Gen 2 / ISO18000-6C standards.

The circuit features a complete analog/RF front-end including rectifier, demodulator, backscattering modulator, a power management unit (PMU) and a short-term memory (STM) that generates the persistence flags. The PMU includes an output supply voltage limiter, internal voltage and current references, built-in power-on-reset (POR), and oscillator. Internal blocks are trimmable via a digital word that can reside in the non-volatile memory of the chip.
