- A 4 Gbit/s radio link using impulse-based on-off keying at 60 GHz is demonstrated. The input baseband signals are transferred to radio frequency wavelets through direct conversion, by switching a GaAs gated tunnel diode oscillator on and off. The wavelet generator drives an antenna directly without any buffer or power amplifier. The peak output power is - 11 dBm at a power consumption of 30 mW. The signals are detected with an energy detector and the link has a bit error rate < 10(-12) for distances shorter than 35 cm.

- The generation of a canonical signed digit representation from a binary representation is revisited. Based on the property that each nonzero digit is surrounded by a zero digit, a hardware-efficient conversion method using bypass instead of carry propagation is proposed. The proposed method requires less area per digit and the required bypass signal can be generated or propagated with only a single NOR gate. It is shown that the proposed converter outperforms previous converters and a look-ahead circuitry to speed up the generation of bypass signals is also proposed.
