摘要： This invention is generally concerned with digital-to-analogue converters and more particularly relates to techniques for reducing signal dependent loading of reference voltage sources used by these converters. A differential switched capacitor digital-to-analogue (DAC) circuit (500) comprises first and second differential signal circuit portions (500a,b) for providing respective positive and negative signal outputs with respect to a reference level, and has first and second reference voltage inputs (112,114) for receiving respective positive and negative references. Each of said first and second circuit portions comprises an amplifier (102a,b) with a feedback capacitor (104a,b), a second capacitor (106a,b), and a switch (108a,b, 110a,b) to switchably couple said second capacitor to a selected one of said reference voltage inputs to charge the second capacitor and to said feedback capacitor to share charge with the feedback capacitor. The switch of said first circuit portion is further configured to connect said second capacitor (106a) of said first circuit portion to share charge with said feedback capacitor (104b) of said second circuit portion; and the switch of said second circuit portion is further configured to connect said second capacitor (106b) of said second circuit portion to share charge with said feedback capacitor (104a) of said first circuit portion. This enables the second capacitors to in effect be alternately pre-charged to positive and negative signal-dependent nodes so that, on average, signal dependent loading of the references is approximately constant.

摘要： A method and system facilitating selection of participants in multiplayer online electronic games. The method provides an efficient procedure for players to host and join new instances of multiplayer online electronic games, as well as providing a scheme that enables players to join multiplayer online electronic games that are already in progress. The method is implemented through a gaming utility that runs on each player's electronic device (e.g. PC) and interacts behind the scenes with an online messaging service. Player hosts are enabled to select players from a list of contacts provided by the online messaging service who they want to invite to join a chat session. A selected multiplayer online electronic game is selectively launched on all of the player's computers through a single command issued by the host. Additionally, the gaming utility provides players with a list of existing chat sessions being hosted by other players so as to enable the players to join multiplayer online electronic games that are already in progress. The system includes a plurality of electronic devices linked in communication across a communications network, such as a LAN or the Internet. Each electronic device is operatively coupled to a headset having a pair of headphones and a microphone. The headset is worn by a player, enabling the players to verbally communicate with others in a verbal chat session.

摘要： An amplifier is disclosed, having an input stage connected to an output stage. The input stage is connected between a positive supply rail and a ground rail and has an input terminal arranged to receive an input signal. The output stage is connected between a positive supply rail and a negative supply rail and has an output terminal. The output stage is adapted to generate an output signal, which is dependent on a received input signal, at the output, and is further adapted such that, in use, a quiescent voltage at the output terminal is at a selected value between a voltage on the positive supply rail and a voltage on the negative supply rail. For driving a grounded load, the quiescent output voltage is preferably zero volts. In preferred embodiments, the input and output stages are formed on a common substrate using CMOS technology, the output stage including one or more NMOS devices having a triple-well structure. A corresponding method of driving a grounded load is also disclosed.
