The optimization is reported of the light absorber layer thickness of InSb p⁺-p^--n⁺ photodiodes grown by MBE on GaAs(001) substrates.An Al_0.17In_0.83Sb barrier layer between p⁺ and p^- layers was used to reduce the diffusion of photoexcited electrons, allowing rectifying characteristics and high photovoltage response at room temperaturePhotodiodes with a junction area of 90 × 90 μm² and p^--layer thicknesses varying from 0.5 to 3 μm were fabricated, demonstrating that photocurrent increased with p^--layer thickness, which is in good agreement with theor. calculationsThe non-biased differential resistance did not increase as expected, possibly owing to an increase in film defect d. with increasing film thickness, which is considered to produce leakage paths through the light absorber layer.Despite the presence of defects on the grown films, photodiodes with a p^--layer thickness of 3 μm showed a 6-fold improvement in the signal-to-noise ratio when compared with that of 0.5 μm.

A 1.8V 36-mW 11-bit 80MS/s pipelined ADC using capacitor and opamp sharing

Author: Youn-Jae Kook ; Seiji Takeuchi ; Koichi Hamashita ; Kaoru Takasuka ; Pavan Kumar Hanumolu ; Naga Sasidhar ; Un-Ku Moon

A new capacitor and opamp sharing technique that enables a very efficient low power pipeline ADC design is proposed. A new method to cancel the effect of signal-dependent kick-back in the absence of sample and hold is also presented. Fabricated in a 0.18-mum CMOS process, the prototype 11-bit pipelined ADC occupies 2.2 mm2 of active die area and achieves 66.7 dB SFDR and 53.2 dB SNDR when a 1 MHz input signal is digitized at 80 MS/s. The SFDR and SNDR are unchanged for 50 MHz input signal. The prototype ADC consumes 36 mW at 1.8 V supply, of which analog portion consumes 24 mW.
