This article introduces the CMOS integrated transceiver circuit EM4095 for RFID applications working with transponders at a frequency of typically 125 kHz. ... Figure 2: EM4095 Block Diagram. EM4095 ...

I would approach the RFID reader using a variation on this circuit; a single transistor regenerative receiver which is just oscillating at 125 kHz, but whose oscillation is quenched momentarily ...

In passive RFID technology, a "reader" transmits a radio signal that is picked up by the RFID tag. The tag converts the AC of the radio signal into DC in order to power internal circuits. Those ...

1. This simple, common circuit arrangement for the Schottky-enhanced PIN limiter is reflected in its small signal equivalent circuit. Since the limiter must precede the receiver’s gain stages to ...

The need arises in virtually all electronic circuits, especially in RF circuit design. “ Back to Basics: Impedance Matching (Part 1) ” discusses the use of a transformer as a basic way to ...

Researchers in Sunchon, South Korea, have printed RFID circuits on plastic films using a combination of industrial methods: roll-to-roll printing, ink-jet printing, and silicone rubber-stamping.

One of the dreams of makers the world over is to be able to print electronic circuits on more or less any surface using a desktop printer. The great promise is the possibility of having RFID ...
