Abstract: The process involves providing a gate current to two differential pair of transistors (Q10, Q11, Q20, Q21) that are mutually disconnected statically and connected dynamically. A local oscillator (LO) commending the transistors is made inactive in a mode of gate current calibration. The transistors are calibrated by canceling a base current. A tension difference applied to bases is adjusted until close to an output voltage. Independent claims are also included for the following: (a) a device for transportation of frequency (b) a component of a system of wireless communication comprising the device of transportation of frequency.

IPC: H03D7/14

Abstract: The frequency converter has a transconductance module receiving the input signal and a current switching module connected to the output. The common mode static currents (Iif1, Iif2) in the output are regulated in a closed loop in response to a current proportional to a reference current (Iref) independent of the static currents at the output of the transconductance module.
