The transconductance stage receives an RF signal, and outputs a current corresponding to a voltage of the RF signal. The switching stage switches the current which is outputted from the transconductance stage in response to a local oscillation signal, for frequency conversion the RF signal into an intermediate frequency (IF) signal. The load stage is connected between the switching stage and a supply voltage terminal. The current bleeding circuit is connected parallel with the switching stage, especially, embodying inverter structure with transconductance stage to get not only current bleeding effect but also current reuse effect, and one resonant inductor for reducing noise which is generated in parasitic capacitance at node between transconductance stage and switching stage. The bias stage is connected between the transconductance stage and a ground terminal, and has the switched biasing technique for allowing not only the stable bias current but also lowering the flicker noise.

Abstract: Disclosed herein is a method of constructing an underground pile having an expanded bulb on a lower end or an intermediate portion thereof. In the method of the present invention, liquefied grout is charged into a hole bored in the ground, and a rapidly expanding metal compound of metal powder and a metal salt is inserted into the grout. Thereafter, the rapidly expanding metal compound is exploded in the grout before the grout is cured, so that a portion of the hole is widened and the grout is charged into the widened portion. According to the present invention, the expanded bulb which protrudes outwards can be easily formed at a predetermined position of the underground pile and, simultaneously, the soil around the pile can be hardened. Furthermore, the construction period and construction cost of the pile having the expanded bulbs are markedly reduced. As well, the underground pipe having the expanded bulb according to the present invention can exhibit superior supporting force despite having reduced length and diameter compared to the straight pile. Therefore, the present invention makes it possible to provide superior ground reinforcing ability despite using a reduced number of piles compared to the conventional art.
