A Current-Mode Optoelectronic Receiver IC for Short-Range LiDAR Sensors in 180 nm CMOS

A wide spectral range single-photon avalanche diode fabricated in an advanced 180 nm CMOS technology.

We present a single-photon avalanche diode (SPAD) with a wide spectral range fabricated in an advanced 180 nm CMOS process. The realized SPAD achieves 20 % photon detection probability (PDP) for wavelengths ranging from 440 nm to 820 nm at an excess bias of 4 V, with 30 % PDP at wavelengths from 520 nm to 720 nm. Dark count rates (DCR) are at most 5 kHz, which is 30 Hz/μm2, at an excess bias of...

A 1 Gb/s Differential Input Threshold Detection Based BPSK Receiver For IR-UWB Communication Using 180 nm CMOS Technology

A Low-Power 2.4-GHz Transmitter/Receiver CMOS IC

A 2.4-GHz CMOS receiver/transmitter incorporates circuit stacking and noninvasive baseband filtering to achieve a high sensitivity with low power dissipation. Using a single 1.6-GHz local oscillator, the transceiver employs two upconversion and downconversion stages while providing on-chip image rejection filtering. Realized in a 0.25m digital CMOS technology, the receiver exhibits a noise figu...

5-10 Gb/s 70 mW Burst Mode AC Coupled Receiver in 90-nm CMOS

A low power burst mode receiver architecture is presented which can be used for AC coupled links where low frequency signal components are attenuated by the channel. The nonlinear path comprises a hysteresis latch that recovers the missing low frequency content and a linear path that boosts the high frequency component by taking advantage of the high pass channel response. By optimally combinin...

A Scaleable CMOS Current-Mode Preamplifier Design for an Optical Receiver

We have designed a process-insensitive preamplifier for an optical receiver, fabricated it in several different minimum feature sizes of standard digital CMOS, and demonstrated design scaleability of this analog integrated circuit design. The same amplifier was fabricated in a 1.2 μm and two different 0.8 μm processes through the MOSIS foundry [1]. The amplifier uses a multistage, low-gain-per-...
