摘要: A hybrid IO cell for use with controlled collapse chip connection, wirebond core limited, wirebond IO limited, and wirebond inline chip designs is provided. A method of designing the hybrid IO cell includes designating a technology, determining a minimum pad width of the technology, and determining a minimum pad spacing of the technology. The method also includes determining a width of the hybrid IO cell based on the minimum pad width and the minimum pad spacing, setting a length of the hybrid IO cell equal to the determined width, and storing a definition of the IO cell in a library stored on a computer useable storage medium.

摘要: A latch device having a selectable feedback path includes a retaining device and system isolation device. The retaining device retains within the feedback path a logical value to be written out. The logical value is latched during an active clock signal. The system isolation device disconnects the retaining device from the feedback path during a write operation. Then, when the logical value is written out, the system isolation device reconnects the retaining device. Thus, the feedback path of the latch device may be disconnected to allow for a change in the latch state without overdriving a feedback inverter.

摘要: A receiver and level converter circuit is disclosed which may be used, for example, in converting low-level logic or other signals to high-level signals. In one embodiment, the circuit includes a differential amplifier having two feedback loops to provide an output signal having hysteresis, for increased gain, better noise margin and compensation. Each feedback loop includes a nonlinear difference network. In a preferred embodiment, the circuit is implemented in BICMOS technology, uses out-of-phase FETs as pull-down devices, and may be used to convert ECL-level signals to CMOS or BICMOS-level signals.
