Abstract:
A voltage comparator ( 1 ) has a high switching speed and simplicity of design. It minimizes pulse-width distortion of input digital signals when functioning as a digital input buffer in high speed communications applications. In addition it provides a simple hysteresis circuit ( 31 ) that is easily tuneable with a reference current. The hysteresis circuit ( 31 ) is dependent on a reference current. This current may be chosen to have a proportionality to temperature, supply, or another selectable parameter, and may be programmable, in order to create the desired hysteresis performance.

Claim (Index 1):
A voltage comparator comprising a first stage amplifier comprising a current source connected to the sources of first and second input switches and first and second load switches, and a final stage amplifier comprising first and second input switches and first and second load switches, wherein in said first stage amplifier:\n the first input switch is linked to a voltage input, and the second input switch is linked to a voltage input, and the first load switch is biased by the first input switch, and the second load switch is biased by the second input switch, and wherein the first stage amplifier load switches are configured as diodes, with their gates connected to their drains, wherein current sources are coupled to the drains of the first stage amplifier input switches, each of which has a drain feed into the gate or drain of the first stage amplifier load switches, and wherein the drain connection of the first stage amplifier input switches connects to a terminal of hysteresis circuit switches of a hysteresis circuit in which said hysteresis circuit switches connect together at another terminal with a current source, to vary current flowing in the first stage amplifier load switches in response to the state of the output with the purpose of creating a hysteresis voltage and in which said hysteresis circuit switches are configured to act as complementary switches.
