集成电路器件微波损伤效应实验研究

 主要介绍了微波脉冲参数变化对集成电路器件微波易损性的影响。实验表明：集成电路器件损伤功率阈值随着微波频率的增加而增大，随着脉冲重复频率的增加而减小。随脉冲宽度的变化较为复杂，总体是随着脉冲宽度的增加损伤功率阈值逐渐降低，但存在一拐点区域（约100ns），在此区域后，脉冲宽度增加但器件损伤功率阈值变化不甚明显。器件损伤功率阈值基本呈正态分布，且方差较小，因此，器件的损伤概率近似于0~1分布。

Realization of optoelectronic integrated transmitter and receiver for POF Applications

The optoelectronic integrated transmitter and receiver for 650 nm plastic optical fiber (POF) communication applications realized in 0.5 μm BCD (Biplor, CMOS and DMOS) process is first described in this paper. The 650 nm resonant cavity light emitting diode (RCLED) is used as light source. It is first proposed for optoelectronic integration of the transmitter by bonding RCLED to the driver chip. Temperature compensation technology is employed in the driver circuit to compensate for the modulation current. In the monolithic optoelectronic integrated receiver, large area multi-finger PIN photodetector (PD) that is compatible with standard IC process, transimpedance amplifier and post amplifier are presented. Measurement results show that the responsivity and capacitance of PD is 0.25 A/W and 5 pF, respectively. The sensitivity of receiver is −14.6 dBm at 180 Mb/s and BER is less than 10⁻⁹ for 650 nm input light by POF. A clear eye diagram is demonstrated for 180 Mb/s PRBS. These indicate that optoelectronic integrated chips can be employed in high-speed POF-based Fast Ethernet systems for broadband access network applications.     

A new digital readout integrated circuit (DROIC) with pixel parallel A/D conversion and reduced quantization noise

This paper represents a novel digital readout for infrared focal plane arrays with 2.33 Ge⁻ charge handling capacity while achieving quantization noise of 161 e⁻. Pixel level A/D conversion has been realized by pulse frequency modulation (PFM) technique supported with a novel method utilizing extended integration that eliminates the requirement for an additional column ADC. Digital pixel operates with two phases; the first phase is as ordinary PFM in charge domain and the second phase is in time domain, allowing the fine quantization and low quantization noise. A 32 × 32 prototype has been manufactured and tested. Measured peak SNR at half well fill is 71 dB with significant SNR improvement for low illuminated pixels due to extremely low quantization noise. 32 × 32 ROIC dissipates only 1.1 mW and the figure of merit for power dissipation is measured to be 465 fJ/LSB, compared to 930 fJ/LSB and 1470 fJ/LSB of the state of the art.
