Abstract

A pulse on edge circuit includes a first pull up transistor having its gate terminal coupled to a delayed control signal and a second pull up transistor having its gate terminal coupled to an inverted delayed control signal. A first and second pull down transistors are coupled in series between the first pull up transistor and a low voltage bias, wherein the gates of the first and second pull down transistors are coupled to the delayed control signal and inverted control signal, respectively. A third and fourth pull down transistors are coupled in series between the second pull up transistor and the low voltage bias. The gates of the third and fourth pull down transistors are coupled to a control signal and the inverted delayed control signal, respectively.

Claims (12)

1. A negative pulse on edge circuit, comprising:

a first pull up transistor having its gate terminal coupled to a delayed control signal;

a second pull up transistor having its gate terminal coupled to an inverted delayed control signal, wherein the first and second pull up transistors are coupled together at a first terminal and coupled to a power source at a second terminal;

a first and second pull down transistors coupled in series between the first pull up transistor and a low voltage bias, wherein the gate of the first pull down transistor is coupled to the delayed control signal and the gate of the second pull down transistor is coupled to an inverted control signal; and

a third and fourth pull down transistors coupled in series between the second pull up transistor and the low voltage bias, wherein the gate of the third pull down transistor is coupled to a control signal and the gate of the fourth pull down transistor is coupled to the inverted delayed control signal and wherein an output pulse signal is generated from the first terminal, wherein the first and second pull up transistors are coupled.

2. The circuit of claim 1 , comprising an inverter for generating the delayed control signal from the inverted delayed control signal.

3. The circuit of claim 1 , comprising a timing delay for generating the delayed control signal from the control signal.

4. The circuit of claim 3 , wherein the timing delay includes a plurality of inverters.

5. The circuit of claim 4 , wherein each of the plurality of inverters includes a first transistor for a resistance and a second transistor for a capacitance.

6. The circuit of claim 1 , wherein the first and second pull up transistors are PMOS transistors.

7. The circuit of claim 1 , wherein the first, second, third and fourth pull down transistors are NMOS transistors.

8. The circuit of claim 1 , comprising a switch being controlled by the output pulse signal for bypassing a filter.
