This paper presents the design and measurement of an adaptive 3-tap feed-forward equalizer (FFE) integrated circuit (IC) manufactured in 28-nm digital bulk CMOS technology. The driver consumes only 100 mW from a single 1.5 V supply including the vertical-cavity surface-emitting laser (VCSEL) and excluding the input matching circuitry. The 50 Ω input baluns, necessary only for the measurement, are...
In order to extend the battery life time of mobile devices, power consumption should be reduced in case of a transmission at lower data rate (DR). In optical receiver frontends the limiting or main amplifier (LA/MA) is one of the largest power consumers. This paper presents a LA/MA topology where the power can be scaled down while the gain is kept constant when lower bandwidth is required for the...
A transimpedace amplifier (TIA) for optical links with data rate (DR) of up to 30 Gbps is presented. The design uses several bandwidth and gain enhancement techniques such as regulated common-gate, transimpedance boosting by current injection, transimpedance/transadmittance feedback and active inductor. The design is realized in a 28 nm CMOS technology. Since the circuit does not use any passive planar...
