Description

technical field [0001] The invention belongs to the technical field of microwave monolithic integrated circuits, and in particular relates to the design of a millimeter-wave ultra-broadband high-gain low-power consumption low-noise amplifier chip circuit. Background technique [0002] The millimeter wave low noise amplifier circuit is the front stage circuit of the millimeter wave receiver, its performance is directly related to the noise performance of the whole machine, and affects the sensitivity of the whole system. Millimeter-wave amplifiers with broadband, low noise, high gain and low power consumption are the difficulties that restrict high-performance millimeter-wave receiver systems. [0003] In order to increase the gain, the traditional circuit design method is to directly cascade multiple transistors, but the working current of multiple transistors cascaded is the sum of several transistors, so the power consumption is large; and the working bandwidth of multiple...
