摘要： A high-speed digital received signal strength indicator (RSSI) circuit is provided. The high speed digital RSSI circuit includes an amplifying unit which includes a plurality of amplifiers connected in series for amplifying a received signal through multiple stages, a thermal code generating unit for generating a thermal meter code of 2n bits by using a pair of output signals that are outputted from each of the amplifiers of the amplifying unit and have an inversed phase to each other, and a binary code converting unit for converting the thermal meter code of 2n bits into a binary code of n+1 bits, and thus outputs the binary code as digital RSSI data for controlling the gain of the received signal

摘要： A programmable variable gain amplifier includes at least three amplifiers. A first amplifier is configured to amplify an input signal. A second amplifier, which includes a programmable output load stage, is configured to receive an output signal from the first amplifier and to output a first differential output signal. The output load stage includes multiple first switches and multiple first diode-connected transistors that are open-circuited or short-circuited by the first switches. A third amplifier, which includes a programmable current mirror input stage, is configured to receive the first differential output signal from the second amplifier through the current mirror input stage and to output a second differential output signal. The current mirror input stage includes multiple second switches and multiple second transistors that are open-circuited or short-circuited by the plurality of second switches. The second transistors respectively form current mirrors with the first diode-connected transistors corresponding to the second transistors.
