The very large number of channels and high data rates in modern particle physics experiments put very stringent requirements on the acquisition of data. To reduce the cost as well as the number of cables required to transport the data from detector to counting room, it is necessary to use very large scale integrated circuits for pre-processing the data right on the front-end circuit boards. Als...

A simple optoelectronic circuit integrated monolithically in GaAs to implement sigmoidal neuron responses is presented. The circuit integrates a light-emitting diode with one or two transistors and one or two photodetectors. The design considerations for building arrays with densities of up to 10(4) cm(-2) are discussed.

A clock recovery circuit is a key component in optical communication systems. In this paper, an optoelectronic clock recovery circuit is reported that monolithically integrates a resonant tunneling diode (RTD) and a uni-traveling-carrier photodiode (UTC-PD). The circuit is an injection-locked-type RTD oscillator that uses the photo-current generated by the UTC-PD. Fundamental and sub-harmonic c...

This paper presents two highly integrated receiver circuits fabricated in InP heterojunction bipolar transistor (HBT) technology operating at up to 2.5 and 7.5 Gb/s, respectively. The first IC is a generic digital receiver circuit with CMOS-compatible outputs. It integrates monolithically an automatic-gain-control amplifier, a digital clock and data recovery circuit, and a 1 : 8 demultiplexer, ...

We present an optoelectronic module called the equivalency-processing parallel photonic integrated circuit (EP(3)IC) that is created specifically to implement high-speed parallel equivalence searches (i.e., database word searches). The module combines a parallel-computation model with multiwavelength photonic integrated-circuit technology to achieve high-speed data processing. On the basis of s...

A new generation of high-frequency integrated circuits is presented, which is called substrate integrated circuits (SICs). Current state-of-the-art of circuit design and implementation platforms based on this new concept are reviewed and discussed in detail. Different possibilities and numerous advantages of the SICs are shown for microwave, millimeter-wave and optoelectronics applications. Pra...
