ABSTRACT:
An electronic circuit having a signal current reflection element, includes a low pass filter for limiting a bandwidth of a control signal which is supplied to a gate of a transistor to which at least an input current is flowing in a current mirror circuit as the signal current reflection element, and a feedforward signal path including a capacitance which is provided between an input terminal of the current mirror circuit and other terminal of the electronic circuit including the current mirror circuit. Accordingly, it is possible to provide the electronic circuit having a miniaturized circuit scale of the current mirror circuit without using a gate grounded circuit and a bias circuit thereof, and an elective high frequency characteristic.
