Abstract: A single integrated circuit (12). The integrated circuit comprises a first circuit (14x) having a data path, the first circuit consisting of a first number of logic gates for performing a plurality of logic functions. The integrated circuit also comprises a circuit (22x) for indicating a potential speed capability of the data path. The circuit for indicating comprises a second number of logic gates (82, 92) for performing the plurality of logic functions, wherein the second number is less than the first number. The circuit for indicating also comprises additional circuitry (88, 98) for representing parasitic characteristics in the data path.

Abstract: Low voltage transistors are used in high voltage environment. The low voltage transistors may be used in the path of processing of a signal to increase the throughput performance. By using high voltage supply associated with the high voltage environment, a higher SNR may be attained. Various techniques are implemented to ensure that the low voltage transistors are not damaged by prolonged exposure to high voltages.

Abstract: A clamping circuit containing a transistor and a current amplifier. The transistor is designed to turn on when the voltage at a node exceeds (falls below) a specified upper (lower) level. The current amplifier is designed to draw substantial amount of current when the transistor is turned on to clamp the voltage at the node to the desired level.
