摘要： A bandgap type, thermal protection circuit for an integrated circuit does not require the use of a comparator and a voltage divider of the bandgap voltage. By contrast, the simplified thermal protection circuit of the invention utilizes a first transistor for mirroring the current flowing through the bandgap circuit through a second transistor that is functionally connected between the output node and ground. The control terminal of the second transistor is connected to a temperature dependent voltage derived from the bandgap circuit. The crossing point between the characteristic of such a temperature dependent voltage and of the VBE characteristic of the second transistor versus temperature determine the required transition on the output node.

摘要： A time delay filter includes at least one field-effect transistor of the MOS type and at least one bipolar transistor having their respective base and gate terminals connected together. The bipolar transistor is coupled to an input terminal through a drive transistor, and the field-effect transistor is coupled to an output terminal. The charge time for the gate capacitance of the field-effect transistor, using the low base current of the bipolar transistor, enables high-frequency noise to be filtered out of input digital signals.
