The circuit consists of an optical receiver front-end and time-to-digital converter. Received pulse amplitude detectors are also included to correct measurement for walk error. The IC is fabricated in a 0.18-mum BiCMOS process. The receiver front-end achieves a 2.3 GHz bandwidth and NF lower than 5 dB. The system

The 3.3mm×2mm die is implemented in a 50GHz-fT 0.8 μm silicon bipolar technology and includes two down-converter channels and a 10.2GHz local oscillator synthesizer. The receiver features a 7.8dB SSB NF, an output P1dB of 5dBm with 32dB conversion gain and phase noise of -96dBc/Hz at 100kHz offset from

This work investigates the design of a monolithic switch-matrix for dual-user digital-satellite applications in silicon bipolar technology. The circuit performs a 29-dB isolation between the two output channels and an output 1-dB compression point of +5 dBm. The good overall performance, despite the monolithic approach, is due to the

The monolithic transformer's parameters were optimized through theoretical analysis of the circuit performance (i.e., gain, noise and linearity). The system was fabricated in a 0.13-mum CMOS process. The measurements show a receiver conversion gain of 20 dB and a

The ADFLL uses a high resolution single-bit digital ΣΔ frequency discriminator in the feedback path and a ΣΔ phase accumulator in the reference path, achieving fractional resolution. The ADFLL uses a digital IIR-based loop filter followed by
