RECEPTION DEVICE AND ELECTRONIC DEVICE USING THE SAME
摘要
<p>Provided is a reception device including: a stepwise-variable gain amplifier; and a controller for controlling the gain of the stepwise-variable gain amplifier in accordance with a signal quality value of a demodulator. The stepwise-variable gain amplifier is changed with N gains from the first to the N-th gain. When the controller changes the gain of the stepwise-variable gain amplifier, the gain number is changed one by one. Thus, it is possible to realize a reception device using the stepwise-variable gain amplifier requiring a low control voltage as compared to a continuously-variable gain amplifier.</p>
