A precise timing generator is presented which forms the heart of a wideband impulse radio or radar system. The circuit is implemented in a 45 GHz Si/SiGe HBT technology, and can produce a pulse inside a 100 ns window with an accuracy of 2 ps and a jitter of less than 10 ps. The integrated circuit contains a mixture of analog, digital, and RF functions, consumes 0.5 W, and operates at a clock rate of up to 2.5 GHz.
