Latest Patents

One of Takahashi's latest patents is the "Offset Correction Circuit." This invention quickly detects an offset and prevents the cutoff of low-frequency signals. The offset detection circuits smooth the output of a variable gain amplifier at a predetermined time constant and detect the offset, which is a DC component. The detected offset is then added to the input of the variable gain amplifier by an adder, correcting the offset in the output of the variable gain amplifier. The time constant in the offset detection circuit is adjustable based on the resistance values of the variable resistors. It changes to a small time constant when the gain of the variable gain amplifier is altered and subsequently to a large time constant.

Another notable patent is the "Frequency Modulation-Type Transmitting Apparatus." This invention features a front-end processing circuit that applies predetermined processing to an input signal and outputs a processed signal. A frequency modulation circuit applies frequency modulation to the output signal of the front-end processing circuit. The front-end processing circuit includes a variable amplifier and a level detector. The variable amplifier receives a feedback signal and amplifies a signal by an amplification factor corresponding to the feedback signal. The level detector outputs the feedback signal to the variable amplifier based on the level of a signal obtainable in a circuit succeeding the variable amplifier. This design ensures that the signal supplied to the frequency modulation circuit is maintained at a constant level.
