Abstract
In some examples, an integrated circuit device includes a sampling switch configured to sample an input signal. The integrated circuit device also includes a first evaluation unit configured to receive the sampled input signal from the sampling switch and evaluate the sampled input signal. The integrated circuit device further includes a second evaluation unit configured to receive the sampled input signal from the sampling switch and evaluate the sampled input signal. The sampling switch is configured to deliver the sampled input signal to the first evaluation unit and deliver the sampled input signal to the second evaluation unit.
Claims21
An integrated circuit device comprising:
- a sampling switch configured to sample an input signal;
- a first evaluation unit configured to:
- receive the sampled input signal from the sampling switch;
- and
- evaluate the sampled input signal;
- and
- a second evaluation unit configured to:
- receive the sampled input signal from the sampling switch;
- and
- evaluate the sampled input signal,
- wherein the sampling switch is configured to:
- deliver the sampled input signal to the first evaluation unit;
- and
- deliver the sampled input signal to the second evaluation unit, and
- wherein an operating voltage range of the sampling switch is greater than an operating voltage range of at least one of the first evaluation unit or the second evaluation unit such that the sampling switch is configured to receive the input signal at a first voltage level and the at least one of the first evaluation unit or the second evaluation unit is configured to receive the sampled input signal at a second voltage level, and
- wherein the second voltage level is lower than the first voltage level.
(canceled)
A method comprising:
