    Abstract: Power switch units for microelectronic devices are disclosed. In one aspect, a microelectronic device may include a functional circuit, and a power switch unit to switch power to the functional circuit on and off. The power switch unit may include a large number of transistors coupled together. The transistors may include predominantly positive-channel, insulated gate field effect transistors, which have a gate dielectric that includes a high dielectric constant material. Power switch units having such transistors may tend to have low power consumption. In an aspect, an overdrive voltage may be applied to the gates of such transistors to further reduce power consumption. Methods of overdriving such transistors and systems including such power switch units are also disclosed.

    Abstract: A two stage fully differential amplifier has been designed which works, in tandem with a TX-FIR, as a linear equalizer at low frequencies, not covered by the TX-FIR, and also acts as a linear amplifier at higher frequencies which are equalized by the TX-FIR. The amplifier as a frequency response which does not attenuate signals frequencies less than one twentieth of baud rate, creates gain peaking ion the region between one twentieth and one tenth of baud rate and maintains flat peak gain up to half of baud rate. Different aspects of the frequency response curve (such as dc gain, max gain and zero frequency) are completely programmable. Also, the differential amplifier has been designed from low power and process, voltage and temperature insensitive frequency response.

    Abstract: A method and system for establishing a call between two endpoints residing on different media gateways in a decomposed voice over packet architecture. Cluster attributes identifying alternate bearer possibilities are exchanged between media gateways as part of capabilities negotiation which occurs during call setup conducted by an external call control element over a core network. The media gateways analyze the cluster attributes to determine whether bearer possibilities exist apart from the core network. If an alternate bearer possibility exists, the alternate is employed and the call is established via the alternate bearer directly between the media gateways, thus bypassing the core network.

    Abstract: A method for converting packet-based voice data of a first format directly to packet-based voice data of a second format, and vice versa. Data from networks using non-compatible packet-based voice technologies, for example, VoATM and VoIP, are interworked for direct conversion. Connection is set between an edge gateway of a first voice packet network, having data in a first format, and an interworking unit (IWU). Another connection is set between this IWU and an edge gateway of a second voice packet network, having data in the second format. The IWU is controlled by a single call agent that co-ordinates the conversion, at the IWU, between the two packet formats. Because it has this capability, this call agent is also called the “conversion server”. This call agent may be identical to the call agent used to control one or both edge gateways that use different packet based technologies.

    Abstract translation: 一种用于将第一格式的基于分组的语音数据直接转换为第二格式的基于分组的语音数据的方法,反之亦然。 使用不兼容的基于分组的语音技术的网络(例如VoATM和VoIP)的数据可以互相直接转换。 在具有第一格式的数据的第一语音分组网络的边缘网关和互通单元(IWU)之间设置连接。 在该IWU和具有第二格式的数据的第二语音分组网络的边缘网关之间设置另一连接。 IWU由单个呼叫代理控制,协调IWU在两种数据包格式之间的转换。 由于具有此功能,此呼叫代理也称为“转换服务器”。 该呼叫代理可以与用于控制使用不同的基于分组的技术的一个或两个边缘网关的呼叫代理相同。
