    Abstract: A device under test (DUT) is tested via a test interposer. The test interposer includes a first set of contacts at a first surface to interface with the contacts of a load board or other interface of an automated test equipment (ATE) and a second set of contacts at an opposing second surface to interface with the contacts of the DUT. The second set of contacts can have a smaller contact pitch than the contact pitch of the first set of contacts to facilitate connection to the smaller pitch of the contacts of the DUT. The test interposer further includes one or more active circuit components or passive circuit components to facilitate testing of the DUT. The test interposer can be implemented as an integrated circuit (IC) package that encapsulates the circuit components.

    Abstract: A Schmitt trigger has a first inverter, a second inverter, a bias means, and a transistor. The inverter has an input and an output. The second inverter has an input coupled to the output of the first inverter and has an output. The bias means provides a first bias voltage on a first output terminal. A magnitude of the bias voltage is selectable by a first input signal. The transistor has a first current electrode coupled to a first power supply terminal, a control electrode coupled to the output of the second inverter, a second current electrode coupled to the output of the first inverter, and a body coupled to the first output terminal. Selectability of the magnitude of the bias voltage provides selectability of the hysteresis of the Schmitt trigger.

    Abstract: A dual bandwidth crystal controlled oscillator is described having a first transconductance amplifier providing sufficient gain to maintain oscillation with an oscillator crystal at a minimum current drain. A second transconductance amplifier is provided which can be selectively coupled to the first transconductance amplifier, thereby augmenting the gain of the first transconductance amplifier to provide the capability for rapid oscillator start-up following battery saver operation. The dual bandwidth crystal controlled oscillator can be utilized in conventional oscillator and frequency synthesizer applications.

    Abstract: A paging receiver includes a nonvolatile memory which is readable for controlling the operation of the paging device and is capable of being partitioned into a plurality of regions. A protect means is also included for allowing modification to a selected region of the nonvolatile memory in response to an unlock signal. In a first embodiment, the unlock signal is externally applied to the paging receiver. In a second embodiment, the unlock signal is generated when a predetermined coded signal stored in the paging receiver matches a received coded signal. In a third embodiment, the protect means further includes a switch means to permit the selected region of memory to be modified while preventing other regions of memory to be modified.

    Abstract: First and second unused bits of a multi-bit mapped register are utilized to control a desired function. Each of the bits are capable of assuming first and second stable states. The control function is enabled when the first bit is in the first state and the second bit is in a second state. The function is disabled when the first bit is in the second state and the second bit is in the first state. The function remains unaltered when the first and second bits are each in the same state.

    Abstract: A phase locked loop (PLL) is provided having a filter with a programmable wide and narrow bandwith. When PLL circuit operation is initiated or when the operational frequency of the PLL is changed by a substantial amount, a phase detector functions to force the filter in a wide bandwith mode to allow fast circuit operation in the transient mode. After the PLL output has settled close to a predetermined frequency, the number of times the output frequency varies above and below the predetermined frequency before reaching a locked state is detected and counted. After the output frequency has varied above and below the predetermined frequency a predetermined number of times, the filter is automatically switched to a low bandwith mode to allow the PLL to operate in a stable manner.
