摘要： A voltage to frequency conversion system may be used in association with clock related applications such as a closed loop oscillator. The voltage to frequency conversion system includes independent current sources that are synchronously operated to generate substantially the same respective output currents under varying temperature and supply voltage conditions. One of the current sources is used to generate a reference voltage, and the other of the current sources is used to charge a capacitor in a predetermined ramp. The capacitor may be selectively charged and discharged based on a frequency of an input signal, and an average of the variable charge voltage of the capacitor may be compared to the reference voltage to generate an analog output signal indicative of frequency.

摘要： A voltage regulator compensation circuit provides power to a dynamic load and includes a power transistor configured to drive the dynamic load, a reference determining transistor configured to establish a voltage reference proportional to a regulated output voltage of the power transistor, and a control circuit coupled to a gate input of both the power transistor and the reference determining transistor. Also included is a comparison engine configured to compare the regulated output voltage and the voltage reference, and a current consuming transistor operatively coupled to an output of the power transistor and configured to provide a varying secondary load. The comparison engine is configured to control the current consuming transistor to increase current draw or decrease current draw from the power transistor based on the difference between the regulated output voltage and the voltage reference.
