Abstract
An apparatus comprising a first circuit and a second circuit. The first circuit may be configured to generate a first signal comprising a series of one or more pulses. The second circuit may be configured to generate a second signal in response to the first signal. The second signal may be configured to control the reset of an external device. In one example, the present invention may be implemented as a power on reset circuit.
Claims22
An apparatus comprising:
- a first circuit configured to generate a first signal comprising a series of pulses;
- a second circuit configured to generate a second signal in response to said first signal and said second signal, wherein said second signal is configured to control a reset of an external device;
- and
- a device configured as a diode, said device coupling said first circuit and said second circuit.
1 more element
An apparatus comprising:
- means for generating a first signal comprising a series of pulses;
- means for generating a second signal in response to said first signal and said second signal, wherein the second signal is configured to control the reset of an external circuit;
- and
- means for coupling said first signal from said first generating means to said second generating means.
1 more element
A method for generating a power on reset signal, comprising the steps of:
- (A) generating said reset signal in response to a periodic signal and said reset signal;
- (B) generating said periodic signal comprising a series of pulses;
- and
- (C) coupling said periodic signal to a generator of said reset signal using a device configured as a diode.
