Abstract: This paper reports the design and experimental characterization of a cryogenic compact low-power 60GHz amplifier for control of electron/hole spin qubits, as elementary building block for monolithic Si quantum processors. Tested at 2 K, the amplifier exhibits $S$ 21 of 15 dB at 59 GHz, BW3dB of 52.5-67.5 GHz, and power consumption of 2.16 mW. Owing to the topology with inductorless active network, the amplifier has a compact core area of O.18×O.19 mm2.
