Latest Patents

Masato Nakakita holds a patent for an innovative amplifier design. This amplifier includes a single-stage or multiple-stage variable gain amplifier that amplifies an input signal with a controlled gain. It features an Automatic Gain Control (AGC) circuit that detects the peak level of a signal outputted from the variable gain amplifier in the final stage. The AGC circuit converts the resultant signal to a digital signal and outputs an AGC control signal for controlling the gain of the variable gain amplifier based on the converted digital signal. Additionally, it incorporates an Electronic Variable Resistor (EVR) control circuit that outputs an EVR control signal according to a signal of setting an attenuation value or an amplification value for EVR inputted from an electronic variable resistor control terminal. The gain control circuit manages the gain of the variable gain amplifier in accordance with at least one of the AGC control signal and the EVR control signal. This design effectively suppresses the occurrence of 'popping' sounds caused by differences in DC voltage due to switching between the AGC circuit and the electronic variable resistor circuit.
