Problems solved by technology

Furthermore, some conventional level-shifting circuits cannot operate properly with data-dependent digital signals (e.g., return-to-zero signals) and are suitable for input signals with fixed duty cycles (e.g., clock signals).
Driving current through the DAC switch from a high-voltage supply or using a power-hungry on-chip low-dropout (LDO) regulator can lead to high power dissipation in existing solutions

Abstract

A low-power level-shift circuit for data-dependent signals includes a buffer circuit, a coupling capacitor, and a biasing circuit. The buffer circuit is biased by a low-voltage domain voltage supply and configured to receive a data-dependent signal. The coupling capacitor is coupled, at a first node, to an output node of the buffer circuit. The biasing circuit is coupled to a second node of the coupling capacitor and a switch. The level-shift circuit can translate a voltage level of the received data-dependent signal to a high-voltage domain that is suitable for proper operation of the switch.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of priority from U.S. Provisional Patent Application No. 61 / 932,689, filed January 28, 2014, the entire contents of which are incorporated herein by reference. technical field [0003] This specification relates generally to broadband communications, and more particularly, but not exclusively, to the technical field of low power level-shift circuits for data-dependent signals. Background technique [0004] High-resolution digital-to-analog converter (DAC) circuits are commonly used in numerous communication circuits. For example, broadband and high-speed (eg, 10 Gigabit) Ethernet communication circuits may use multi-GHz (multi-GHz) and high-resolution DAC circuits. A large value push-pull DAC circuit may include switches (eg, PMOS switches) that may be driven by a high-voltage domain (eg, 3.3V) supply voltage. However, DAC circuits need to be able to operate with data dependent low...
