The prospect is especially interesting to me because, frankly, I envy the analog skills I associate with building a radio receiver. When I browsed the circuit literature in the area, I came across the Silicon Labs collection. One of their chips, the Si4844-A10 caught my attention. This receiver has AM\/FM\/SW capability with all the bells and whistles and it is designed to work with a microprocessor. Best of all, the support components required are mainly associated with the microprocessor display and control functions with only a small amount of antenna support needed. I couldn\u2019t resist taking the plunge.<\/p><\/blockquote>\n","protected":false},"excerpt":{"rendered":"<p>Raymond Genovese from All About Circuits\u00a0has shared his idea of making a full-featured AM\/FM\/SW radio using SiLab&#8217;s Si4844-A10 radio chip, which is the first analog-tuned digital-display digital CMOS AM\/FM\/SW radio receiver IC integrating\u00a0the complete receiver function from antenna input to audio output.
