This paper presents a fully integrated 9-11-GHz shock wave transmitter with an on-chip antenna and a digitally programmable delay circuit (DPDC) for pulse beam-formability in short-range microwave active imaging applications. The resistorless shock wave generator (SWG) produces a 0.4-V peak-to-peak (p-p) shock wave output in HSPICE simulation. The DPDC is designed to adjust delays of shock-wave outputs...
The present paper introduces a resonant clock generation and distribution scheme that uses uniform amplitude and uniform phase standing wave oscillators in order to distribute a high-frequency clock signal with low skew, low jitter, and low power. A suitable distributed resonator for a global clock distribution that is inductively loaded transmission line generating a uniform amplitude and uniform...
This paper describes a 500-Mb/s 12-mW pulsed UWB transceiver in 1.8-mum CMOS technology for sub-meter short-range wireless communication. The transceiver employs two functional blocks for reducing power dissipation: one is an on-chip transformer-based DC-RF pulse power converter and another is an asynchronous RF-baseband direct demodulator. The prototype chip with printed dipole antenna can operate...
This paper presents an inductive-loaded standing-wave clock oscillator. By coupling the oscillators into mesh structure, multi-ten GHz uniform-phase/amplitude global clocks can be distributed over a whole chip. In the mesh structure, finer grid can be employed than the conventional standing-wave technique, and it makes the depth of clock tree very shallow. We designed and fabricated a 17.2GHz oscillator...
A 4-Mb CMOS SRAM (static RAM) with an access time of 25 ns designed for a single 3.3-V supply voltage and a 400-mil DIP (dual-in-line) package, using a 0.5- mu m double-polysilicon and double-aluminum CMOS technology, is presented. A 25-ns address access time was achieved by a dynamic bit-line-load circuit scheme combined with an address transition detector (ATD), divided word line structure, and...
