In accordance with an embodiment, a transceiver includes a bidirectional data transmission circuit coupled to a direction control circuit and method for transmitting electrical signals in one or more directions. The direction control circuit generates a comparison signal in response to comparing input/output signals of the bidirectional data transmission circuit. Transmission path enable signals are generated in response to the comparison signal.

Bidirectional transceiver and method

In one embodiment, a start-up controller for a PWM power supply controller is formed to generate a current that is substantially constant for changes in temperature and for changes in an output voltage received by the start-up controller.

Method of forming a start-up device and structure therefor

In one embodiment, a multi-function signal sensor is configured to receive a signal having a plurality of states and to offset the input signal by a first amount for values of the input signal that are greater than a first value.

Single pin multi-function signal detection method and structure therefor

A circuit and a method for nullifying temperature dependence of a circuit characteristic. The circuit includes a plurality of transistors configured such that they generate a gate voltage that includes a threshold voltage as a component. The gate voltage is applied to a transistor to generate a current that is proportional to a process transconductance parameter. The current is applied to a comparator having a differential pair of transistors, wherein each transistor has a process transconductance parameter. The circuit takes the ratios of the process transconductance parameter associated with the current to that of each transistor of the differential pair. By rationing the process transconductance parameters, temperature dependence is nullified or negated. The ratios can be used to set the hysteresis voltage of the comparator.

Method for nullifying temperature dependence and circuit therefor

In one embodiment a bus hold circuit decouples an inverter of the bus hold circuit from an operating voltage responsively to an input receiving a signal having a voltage that is approximately equal to or greater than the value of the operating voltage.

Over-voltage tolerant bus hold circuit and method therefor

A method of forming an output transistor ( ) protects the output transistor ( ) from overvoltage conditions on an output ( ). The body of the output transistor ( ) is coupled to the gate of the transistor ( ) prior to the high voltage being applied to the output ( ).
