Abstract
A high band weighting circuit of a noise reduction circuit is disclosed. For elevating a mid and high frequency component gain comparing with a low frequency component among input signal, the high band weighting circuit comprises a capacitor a dividing means a first voltage-to-current converting circuit, a second voltage-to-current converting circuit, a first current mirror circuit outputting a third current signal corresponding to a first current signal of the first voltage-to-current converting circuit, a second current mirror circuit coupling a fourth current signal to the output terminal corresponding to a second current signal of the second voltage-to-current converting circuit, and a third current mirror circuit coupling a fifth current signal to the output terminal corresponding to a third current signal of the first current mirror circuit. Accordingly, the high band weighting circuit can simplify circuit construction and reduce mismatching by coupling outputs of the voltage-to-current converting circuits to output terminal through current mirror circuit.
