Abstract
Mechanisms for reducing amplitude-modulated noise in a wireless transceiver are generally described. In one example, an apparatus includes a radio-frequency identification (RFID) transceiver, a digital-analog converter (DAC) coupled with the transceiver, a reconstruction filter coupled with the digital-analog converter, and hold logic associated with the reconstruction filter to enable the reconstruction filter to hold its output voltage.
Claims15
An apparatus comprising:
- a wireless transceiver;
- a digital-analog converter (DAC) coupled with the transceiver;
- a reconstruction filter coupled with the digital-analog converter;
- and
- hold logic associated with the reconstruction filter to enable the reconstruction filter to hold its output voltage.
2 more elements
A method comprising:
- holding an output voltage of a reconstruction filter at a constant value via a hold logic circuit, the reconstruction filter being coupled to the DAC;
- and
- refreshing the filter connection with the DAC via a refresh logic circuit.
