Abstract: An oscillator circuit including a ring oscillator and a reference current source is provided. The ring oscillator includes an odd number of inverter stages. Each inverter stage includes a first transistor having a first reference threshold that varies over temperature. The reference current source is configured to generate a plurality of currents, where a respective current is applied directly to the drain of a respective first transistor of a respective inverter stage. The reference current source includes a reference transistor that has a second reference threshold that varies over temperature; a resistor coupled between a gate and a source of the reference transistor; a second transistor having a source coupled to the gate of the reference transistor for generating a reference current that flows through the resistor to regulate a voltage of the resistor to the second threshold voltage; and a current mirror configured to generate the plurality of currents.

Abstract: According to an embodiment, a circuit includes a core and low-frequency recovery circuits. The core circuit is configured to bias a resistive sensor used to measure a fly height of a hard disk drive. The core circuit is additionally configured to amplify a high-frequency component of a sensing signal of the resistive sensor, the sensing signal indicating the fly height. The low-frequency recovery circuit is configured to amplify the sensing signal's low-frequency component.
