Principal Analog Mixed-Signal Design Engineer - Gables Search Group

As a member of the design group, the candidate will be responsible for design and validation of FET and BiCMOS circuits for high-speed broadband ICs that serve these applications.

Seeking an RF and Analog Design Engineer to contribute to the development of multi-tens of GHz Transimpedance amplifiers TIAs. These optical interface chips are tightly coupled with our high-performance equalizers. The results of our innovative designs have made our TIAs best in class for coherent long-haul and metro systems as well as PAM4 data center systems. 

In this role you will be responsible for:

• Active circuit design as well as technical leadership.
• Design leading edge transimpedance amplifier design, primarily in Silicon Germanium (SiGe) BiCMOS (Bipolar Complementary Metal Oxide Semiconductor) technology, where circuit performance will need to transcend beyond industry leading products.
• Develop transmission line structures and other millimeter wave structures to enable higher performance than would normally be achievable.
• Design of hi-performance broadband analog circuits for optical front-end receivers.
• Design of various other analog circuits including linear regulators, AGC loop, current/voltage sensors, bandgaps etc.
• Develop microarchitecture of major circuit blocks and guide team of designers to implement them. Work with various technologies including SiGe BiCMOS and CMOS.
• Work with other functional groups to facilitate post-silicon validation, qualification, transition to mass production, and customer support.
