“…The power board has four different output voltages (+10, −10, +5, and −5V), which are used for preamplifiers and the programable gain amplifier (PGA). Another separate +5V power supply for the digital potentiometer on the analog board and the DAC7714 chip and 3.3 V power provide digital logic power for the analog-to-digital converter AD7767 (Yun et al, 2017). The power diagram is shown in Fig.…”

Abstract. As a result of the drastic reduction in shallow mineral resources, the exploitable potential and reserves of proven mines are insufficient, and the mineral resources in deep ground need to be more explored in a more refined way. There are some disadvantages of the existing instruments, such as few channels and slow sampling rate. Therefore, a multiparameter transient electromagnetic instrument with synchronous receiving has been developed and tested. The instrument is composed of two controllers -embedded controller and programmable logic controller -which can provide a diversified information combination for follow-up information processing. Under the grounding electrode source emission mode, the real-time synchronous transient electromagnetic acquisition system of six channels is achieved with a sampling rate of 128 000 samples per second (SPS). The data acquired by the six channels is recorded in the full-time range of the time domain. Furthermore, experiments were carried out in the laboratory, open areas, and actual mine. Through data analysis, the measured data curves of the mining area are highly consistent with the existing geochemical exploration curves and geological profile.

“…Also, the design complexity of a DC-DC converter is much higher than that of a linear regulator. The use of a linear regulator for power management affords design simplicity, less silicon area, low cost, and no ripple [5][6][7][8][9][10][11][12].…”

A linear regulator with an input range of 3.9–10 V, 2.5 V output, and a maximal 500 mA load for use with battery systems was developed and presented here. The linear regulator featured two modules of a preregulator and a linear regulator core circuit, offering minimized power dissipation and high-level stability. The preregulator delivered an internal power voltage of 3 V and supplied internal circuits including the second module (the linear regulator core). The preregulator fitted with an active, low-pass filter provided a low-noise reference voltage to the linear regulator core circuit. To ensure operational stability for the linear regulator, error amplifiers incorporating the Miller compensation technique and featuring a large slewing rate were employed in the two modules. The circuit was successfully implemented in a 0.25 µm, 5 V complementary metal-oxide semiconductor (CMOS) process featuring 20 V drain-extended MOS (DMOS)/bipolar high-voltage devices. The total silicon area, including all pads, was approximately 1.67 mm2. To reduce chip area, bipolar rather than DMOS transistors served as the power transistors. Measured results demonstrated that the designed linear regulator was able to operate at an input voltage ranging from 3.9 to 10 V and offer a maximum 500 mA load current with fixed 2.5 V output voltage.

“…In the proposed LDO, the reference voltage is externally generated. This work [40] (JSSC 2010) [46] (VLSI Table 3.2, save at 1MHz where the LDOs [45,50] reported slightly higher PSRR (only at the 1MHz point) but at lower heavy Iload (50mA vs 100mA in the proposed LDO). Of particular interest, the proposed LDO is the only design that achieves >60dB PSRR throughout the 10MHz frequency range and for 100mA load current range.…”

“…In contrast, the PSRR of state-of-the-art LDOs are high only over a limited loading current range (≤50mA) and/or limited frequency range. The highest loading current (100mA) of the proposed LDO is more than ×2 larger and the lowest loading current (100µA) is an order of magnitude lower than the reported designs [40,45,46,50]. Put simply, the proposed LDO features the highest PSRR for 3-orders of magnitude change in the loading current (100µA to 100mA) whilst the reported competing LDOs suffer lower PSRR despite having a substantially lower loading current range of less than 2-orders of magnitude.…”
