A fully-integrated 40-phase flying-capacitance-dithered switched-capacitor voltage regulator with 6mV output ripple

A switched-capacitor voltage regulator (SCVR) that dithers flying capacitance (C$_textrmFLY$) to reduce output ripple is presented. The proposed technique is implemented in a 40-phase SCVR with 4b C$_textrmFLY$ modulation in 65nm CMOS. At 2.3V input, …

Low power silicon photonic transceivers

We present ultra low power silicon photonic transceivers, including a 320 fJ/bit reverse biased ring modulator integrated with CMOS driver, and a 690 fJ/bit record-low power receiver with sensitivity of -18.9 dBm at 5 Gbps for bit-error-rate of …
