The CMOS Analog Designer contributes to building precision timing circuits, leveraging SiTime’s industry-leading MEMS technology, that span high-performance Networking and Communications Infrastructure market application requirements and ultra-low power Mobile platforms including wearable devices. 


  • Design of Analog and Mixed-Signal circuits, meeting their architectural requirements and technical specifications
  • Contribute to the architectural definition of the design, and also to chip integration
  • Perform the necessary calculations, design and verification simulations to ensure building blocks meet specifications, at the schematic level and after post layout extraction, while fully provisioning for DFT and DFM
  • Work closely with Layout Designers to ensure the layout is completed properly, using all best known methods
  • Document assigned blocks, and hold preliminary and final design reviews
  • Actively participate in the chip bring up, evaluation and characterization, with emphasis on owned blocks
  • Address questions and issues related to his/her blocks raised by cross-functional personnel, such as Product, Characterization, Test, or Application Engineers



  • MS with minimum of 3 years of experience or Ph.D. in Electrical Engineering
  • Design expertise in one of the following areas:
    • PLLs: Sigma-Delta and LC
    • ADCs: preferably > 14 ENOB
    • Temperature Sensor
    • Quartz or MEMS Oscillator
    • Sub-threshold circuits
    • Low-noise regulator and Band gaps
  • Knowledge of programming languages: Matlab, VerilogA, Oceanscript
  • Ability to oversee circuit layout for critical blocks
  • Ability to perform noise analysis
