Abstract: A digital voltage level shifter for converting an input signal with a low voltage swing to an output signal with a high voltage swing comprises a first inverter stage for generating an inverted signal from an input signal, the inverted signal having a voltage swing between a core voltage and ground, and a second inverter stage for producing an anti-phase signal from the inverted input signal, the anti-phase signal having a voltage swing between the core voltage and ground. The first and second inverters each drive a respective thin gate NMOS transistor connected in cascode with a respective NMOS transistor. The sources of the first and second thin gate NMOS transistors are connected to ground. The gates of the NMOS transistors are connected to the output of the respective inverters through a respective capacitor and are referenced to the core voltage through a respective resistor.

Abstract: A television receiver arrangement comprises means for receiving a television signal comprising a plurality of channels and a tuner for tuning in to one of the channels, and capable of receiving data broadcast transmissions. It further comprises a data processor for decoding the data (30), which data processor is adapted to directing the tuner to switch to a channel specified in a resource indicator (16, 17) comprised in the data (30). The data processor is programmed to trigger a channel switch upon receipt and identification of a specific trigger identifier (15) comprised in the data (30).
