摘要： Provided is a distributed amplifier in communication systems, including: an input transmission line; an output transmission line; an input impedance match and an output impedance match, for providing termination of the input transmission line and the output transmission line, respectively and for preventing signal reflection in the input transmission line and the output transmission line, respectively; multi-stage Gm cells with common mode feedback, the input transmission line being coupled to the output transmission line by the transconductance of the Gm cells; and an input gate bias circuit, for providing bias for the multi-stage Gm cells. In at least one of the Gm cells, one inverter performs V/I conversion while other inverters provide negative resistance to control common mode of output voltage and to enhance DC gain of the Gm cell. Due to common mode feedback, no output gate bias is needed.

摘要： In a phase locked loop (PLL), phase shifters shift a phase of an input signal. Based on the phases of the input signal, the shifted signals, and a frequency division output signal, phase frequency detectors (PFDs) generate phase difference signals. In response to the phase difference signals, charge pumps (CPs) control output voltages thereof. Based on the output voltages of the CPs, a voltage controlled oscillator (VCO) outputs an output signal. A frequency divider divides the frequency of the output signal from the VCO to generate the frequency division output signal. A circulator outputs the frequency division output signal to one of the PFDs at a proper timing. A modulator reduces quantization errors of the frequency divider.

The differential amplifying unit is used to amplify a radio frequency (RF) signal and employs a first resonance circuit to force a leakage signal to flow to a first voltage. The current buffer unit is used to amplify the gain of an output signal of the differential amplifying unit and employs a second resonance circuit to force the leakage signal to flow to a second voltage. Finally, the switching unit switches an output signal of the current buffer unit into a base band signal.
