Title: Voltage switch device for switching lower and higher supply voltages, comprising two branches with transistors, and transistors connected as diodes in second branch
Inventor: SEDJAI LEILA
IPC: H03K19/0185
Filed: 2000-11-27
Abstract: The voltage switch (20) comprises transistors (T21,T22) connected in series in the first branch, and a transistor (T23) connected is series with transistors (T24,T25,T26), which are connected as diodes, in the second branch. The drains of transistors (T21,T22) are connected together so to deliver either the supply voltage (Vpp) or the reference voltage, that is the ground potential (GND), as the output voltage in response to a control signal (CDE) applied to the gate of transistor (T21) by the intermediary of an inverter (I2) and to the gate of transistor (T23) directly. The supply voltage (Vpp) is applied to the sources of transistors (T22,T24), and the reference voltage (GND) is applied to the sources of transistors (T21,T23). The voltage switch also comprises as optional a precharge transistor (T27) for applying the reference voltage to the drain of transistor (T24) when the precharge signal applied to the gate of transistor (T27) is active. The drain of transistor (T27) is connected to that of transistor (T24), and the reference voltage (GND) is applied to the source of transistor (T27). In the case of higher supply voltages such as Vpp=12 V, the pulse rise time is about 500 ns, but in the case of lower supply voltages such as Vpp-2.5 V the pulse rise time is about 50 microseconds. The addition of the precharge transistor (T27) improves the switching speed of the voltage switch in the case of lower supply voltages, that is decreases the pulse rise time, which is essential in applications in memory circuits. The transistors (T24,T25,T26) are of p-MOS type; the transistor (T22) is of higher-voltage p-MOS type; and the transistors (T21,T23) are of higher-voltage n-MOS type.

Title: Dynamic channel allocation with internet network link
Inventor: JACOB JEAN-FRANCOIS
IPC: H04L12/801
Filed: 2001-02-22
Abstract: At most, N resources, an ISDN line channels or analog links, are allocated to an amount of information (X) conveyed by IP packets. Each channel occupation is charged according to a basic price PB for a time credit CT then for a time unit price PU. The invention aims at optimising resource occupancy in the network, access performance and user costs. The allocation and clearance of the resources are carried out without inertia by processing information with size of data to be received. The communication cost depends on the number of channels actually required for the amount of information. Said amount (X) is compared to N-1 thresholds (SP1, SPN-1) depending on PB, CT and PU. The number of channels allocated in the rank (n) of the threshold (SPn) immediately higher than said amount. The information is systematically transferred in the N channels if rapidity of communication (E2 - E6) is being favoured.
