摘要： A probe head includes analog amplifier inputs, a ground plane, and hundreds of probe leads between the inputs and the pins of a circuit under test. The customer defines the grounded pins of the circuit under test. Non-active probe leads, i.e. leads corresponding to the grounded pins are connected to the ground plane, maximizing the connections between the grounds of the probe and the circuit under test and minimizing unequal ground potentials. The probe circuit is on a probe circuit board, while the connections between the ground plane and the leads are fusible elements on a separate ground personality board. The probe is placed on a simulated circuit under test, the grounded pins on the circuit under test are protected by an insulating cap, and a voltage is placed on the remainder of the pins to fuse the elements corresponding the active probe leads.

摘要： A probe head includes integrated circuit chip inputs, a ground plane on a circuit board, and hundreds of probe leads comprising traces on the circuit board connected between the inputs and a circuit under test. Each trace is about 3 mils wide. There is a DICLAD polytetrafluoroethylene dielectric material of dielectric constant of about 2.2 between the ground and traces. Every other trace is electrically connected to the ground plane. Input resistors are buried in the circuit board and there is an on-chip input divider network. The customer defines the grounded pins of a circuit to be tested. Probe leads corresponding to the grounded pins are connected to the ground plane, maximizing the connections between the grounds of the probe and the circuit under test and minimizing unequal ground potentials.

摘要： A first amplifier channel between an input and output includes an input transistor emitter and a first output transistor emitter connected together to form a first emitter pair. A current source is connected to the emitter pair via a transistor which is controlled by a latch. Programming the latch permits the channel to be turned on or off. The emitter pair is connected to a positive voltage through a resistor and to ground through a diode to force it to a controlled off voltage, which prevents signals from passing when the channel is off. There is a output driver amplifier in a feedback circuit. An outdisable circuit controls the voltage and current of the output driver amplifier to place the output in a state in which it appears electrically as an open circuit when the channel is off. Multiple programmable amplifiers can be combined to make a multiplexer, a selectable gain circuit, or a selectable attenuation circuit, all with high band width and high signal integrity.

摘要： A monitoring system monitors a pressure wave developed in the surrounding ambient environment during inkjet droplet formation. The monitoring system uses either acoustic, ultrasonic, or other pressure wave monitoring mechanisms, such as a laser vibrometer, an ultrasonic transducer, or an accelerometer sensor, for instance, a microphone to detect droplet formation. One sensor is incorporated in the printhead itself, while others may be located externally. The monitoring system generates information used to determine current levels of printhead performance, to which the printer may respond by adjusting print modes, servicing the printhead, adjusting droplet formation, or by providing an early warning before an inkjet cartridge is completely empty. During printhead manufacturing, an array of such sensors may be used in quality assurance to determine printhead performance. An inkjet printing mechanism is also equipped for using this monitoring system, and a monitoring method is also provided.

摘要： An electronic probe circuit having ac and dc amplifiers and an input compensation subcircuit is enclosed within a trim housing that replicates the electrical effect of the probe housing. The circuit is laser trimmed through ports in the trim housing. The difference between the voltage at 80 nsec and 1.4 .mu.sec points on a step voltage provides a first calibration factor while the difference between the 3 nsec voltage and the 80 nsec voltage provides a second calibration factor. A resistor in the DC amplifier is trimmed to an absolute voltage with a step scan laser cut. A resistor in the AC amplifier is trimmed with a laser L-cut until the difference between the 80 nsec and 1.4 .mu.sec points of the step voltage equals the first calibration factor. A capacitor in the input compensation subcircuit is trimmed until the voltage difference between the 3 nsec and 80 nsec points equals the second calibration factor.

摘要： A capacitively-coupled amplifier circuit includes an amplifier for receiving an input signal via a coupling capacitance and for amplifying the input signal to produce an output signal. A resistor provides a bias voltage to the amplifier. The resistor is bootstrapped using positive feedback with a loop gain of slightly less than one. The bootstrapping causes an increase in the value of the resistor to lower the cut-in (pole) frequency of the amplifier. The bootstrapping or feedback circuit includes a roll-off (pole) at a frequency below the roll-off (pole) frequency of the amplifier. This prevents phase shift in the feedback loop from adversely effecting the high frequency response of the amplifier. The resulting amplifier circuit exhibits a wide passband and excellent low frequency response despite having a capacitively coupled input signal.
