<p>A receiver device (1) comprises a gain control portion (40) which regulates a received signal by controlling the opening and closing of a switch (52) which bypasses a first amplifier (12) and providing variable control over the gain of a second amplifier (16), and which also switches the gain of the second amplifier (16) to compensate for gain fluctuations due to the opening and closing of the switch (12). This gain control portion (40) also comprises a digital logic circuit which can program a time offset between the open/closing period of the switch (52) and the switching period of the gain of the second amplifier (16).</p> |
