ABSTRACT:
A temperature-compensated high-speed timing circuit, which is particularly advantageous in read-interface circuits for disk-drive interface. The voltage on the integrating capacitor is compared against a voltage defined by the drop, on a resistor, induced by a current which is the combination of a reference current from a reference current generator with a temperature-dependent current from another current generator.
