Abstract

According to various embodiments, a miniature passive structure for electrostatic discharge protection and input/output matching for a high frequency integrated circuit may be provided. The structure may include: either a transmission line or an inductor for providing at least one electrostatic discharge path; and a capacitor with a first end connected to the transmission line or inductor and a second end connected to ground.

First claim

What is claimed is:

1. A miniature passive structure for electrostatic discharge protection and input/output matching for a high frequency integrated circuit, the structure comprising:
a transmission line for providing at least one electrostatic discharge path; and
a capacitor with a first end connected to the transmission line and a second end connected to ground;
wherein the transmission line comprises an unloaded transmission line.

2. The miniature passive structure of claim 1 , wherein the transmission line comprises a length of about ¼ wavelength.

3. The miniature passive structure of claim 1 further comprising:
an input signal trace, wherein the transmission line is DC connected to the input signal trace at a first end and DC connected to the capacitor at a second end.

4. The miniature passive structure of claim 1 , further comprising:
an input signal trace, wherein the transmission line is DC connected to the input signal trace at a first end and DC connected to the capacitor at a second end.

5. The miniature passive structure of claim 1 ,
wherein the transmission line comprises a high impedance transmission line;
wherein the high impedance transmission line comprises at least one of (i) a coplanar waveguide, (ii) a conductor backed coplanar waveguide, (iii) coax transmission lines, (iv) a microstrip line, or (v) a stripline.
