    • A test mode controller comprises an enable signal generator, a control signal generator, and a latch. The enable signal generator receives a power signal and a second control signal, and generates a first enable signal and a second enable signal respectively to the latch and the control signal generator. The control signal generator receives a power indicating voltage and a reference voltage, and generates the first control signal to the latch when the first enable signal is enabled. The latch receives the first control signal, and generates the second control signal according to the first control signal when the second enable signal is enabled. The second control signal controls a chip to operate in a test mode or a normal mode. Accordingly, the test mode controller may reduce the test time without a test pin, and may also reduce the chip area and the package cost.

    • A circuit apparatus includes an input end, an output end, an enable module, a first function module and a second function module. The enable module couples to the input end for receiving an input voltage and outputs an enable signal while the input voltage falls within a first voltage scope. The first function module couples to the enable module and the output end, and performs a test mode according to the enable signal so as to output a test result to the output end. The second function module couples to the input end for receiving the input voltage via the input end and performs a standard mode while the input voltage falls within a second voltage scope.

    • A well logging tool apparatus is disclosed for conducting measurements in a borehole environment surrounding a borehole that traverses a subsurface formation. The apparatus includes an elongated conductive mandrel having a longitudinal axis, an antenna array positioned about the mandrel and including a transmitter for transmitting electromagnetic energy into the formation, and a sleeve positioned about the antenna array. The apparatus further includes a first set of electrodes and a second set of electrodes. Each electrode has an outer end that is exposed on the outer surface of the sleeve for conductive contact with an adjacent conductive borehole environment. Further, the first and second sets of electrodes are spaced longitudinally apart such that the transmitter is positioned longitudinally therebetween. Electrodes of the first and second sets are conductively interconnected with the mandrel such that when the well logging apparatus is operated in a borehole environment having borehole currents therein, one or more current path loops are provided for shorting borehole currents.
