A 2x-oversampling 25Gbps clock and data recovery (CDR) circuit is proposed that employs a charge-based, zero-crossing linearizing phase detector (ZCL-PD). This technique linearizes the conventional ...

Analog designers often need matched resistors. One solution is integrated resistor networks, but what if they don't offer the ...

Researchers have cracked a fundamental optical challenge: how to control both angle and wavelength of light independently—a ...

When light strikes the photodiode’s active region, current flows from cathode to anode. Ideally, this entire photocurrent ...

The D-band (110 - 170 GHz) waveguide-based zero-bias Schottky diode (ZBD) power detector is reported. The design aims to get high responsivity across the band. The circuit is fabricated on a 50 μm ...
