Wideband Distributed Mixers

Tech ID: 29886 / UC Case 2003-466-0

Brief Description

This technology is a simple, novel ultra wideband distributed complementary metal-oxide-semiconductor mixer, which incorporates on-chip distributed transmission line. A wideband distributed mixer is capable of operation over a wide range of frequencies, and can carry large amounts data up to 250 feet, which makes it attractive for military and law-enforcement use.

Suggested uses

• Use in next generation ultra-wideband systems
• Use in high-rate, short-to-medium-range communications
• Ability to locate objects within one inch attractive for military, law-enforcement, and rescue agencies
• Broadband sensing and collision avoidance


• Optimum number of differential cells for best conversion gain.
• Lower power consumption and transmission power
• Lower noise susceptibility and interference
• Ultra-wideband wireless broadcasts are capable of carrying huge amounts of data up to 250 feet 

Full Description

Mixers previously proposed by designers have not utilized a standard complementary metal-oxide-semiconductor process. This technology is novel because utilizes a wideband distributed mixer capable of operation over a wide range of frequencies on a complementary metal-oxide-semiconductor. Wideband mixers are used across many wireless applications, and the mixer can include a variety mixer stages and monolithic transmission lines brought together on a common semiconductor substrate.
The design procedure helps to utilize most efficient number of cells for the best conversion. By having a distributed circuit, an ultra-broadband circuit will be achieved by trading delay with bandwidth. This technology is one of the key circuit blocks in a host of communication systems. Moreover, the number of mixer stages as well as the design architectures and topologies for each stage can be changed according to the needs of the application.
These mixer are designs capable of ultra wideband operation with improved conversion gain, lowered noise susceptibility and power consumption, relaxed input signal requirements, and lowered manufacturing costs.
