  • A low-power compact driver for multistandard physical layer is presented. The proposed driver achieves low power and small area through the voltage-mode driver with trans-impedance configuration and the novel hybrid driver,. In the voltage-mode driver, a trans-impedance configuration alleviates the problem of limited common-mode range of error amplifiers and the area and power overhead due to pre-amplifier. For a standard with extended output swing, only current sources are added in parallel with the voltage-mode driver, which is named a 'hybrid driver'. The hybrid architecture not only increases output swing but reduces overall driver area. The overall driver occupies $0.14mm^2$. Power consumptions under 3.3-V supply are 24.5 mW for the voltage-mode driver and 44.5 mW for the hybrid driver.
