摘要： A linear relationship is established between a gain control signal and an amplification factor (value in dB). Described is a current generation circuit including a first current output section which outputs a first current, a second current output section which outputs a second current proportional to the first current, and a variable-current control section which generates a third current proportional to the first current, divides the third current into a fourth current and a fifth current according to a first control signal, and outputs the fourth and the fifth currents. The current generation circuit outputs a sum of the first and the fourth currents as a reference current, and a sum of the second and the fifth currents as an output current.

摘要： A method and a circuit for generating a clock signal from a clock integrated circuit are introduced herein. A compensation voltage is generated according to a temperature coefficient of a resistor and a clock period of a clock circuit, where the compensation voltage is resistor-corner independent. The clock period of the clock circuit is determined by the resistor and at least one capacitor of the clock circuit. The temperature dependence of the clock period of the clock circuit is reduced according to the compensation voltage.
