摘要： Continuous variable-gain low-noise amplifier. The amplifier continuously adjusts its gain between well-defined high and low values by using a cascode current-steering circuit to partition signal current between two different nodes of an output loading network. A shunt feedback network connected from an intermediate node of the loading network to the input provides negative feedback that linearizes the amplifier as its gain is decreased. The circuit degrades the noise figure at lower gains by varying the gain without directly dumping the signal current to the power supply. The circuit produces only small changes in input and output impedances and preserves an improved reverse-isolation cascode characteristic as the gain is controlled.

A shunt feedback network connected from an intermediate node of the loading network to the input provides negative feedback that linearizes the amplifier as its gain is decreased. The circuit degrades the noise figure at lower gains considerably less than conventional circuits by varying the gain without directly dumping the signal current to the power supply. The circuit produces only small changes in input and output impedances and preserves an improved reverse-isolation cascode characteristic as the gain is controlled.

摘要： Amplitude-adjustable oscillator. The oscillator includes a feedback loop to control the amplitude of an oscillator output signal. The feedback loop includes a pair of clamping transistors, wherein base terminals of the clamping transistors are coupled to an adjustable voltage signal to prevent saturation of the oscillator circuit. The feedback loop also includes a filter to monitor the current flowing through the clamping transistors. The feedback loop also includes an amplifier to compare an output of the clamping transistors to a reference signal, and a reference generator to set an operating bias for the oscillator.

A kilt is folded into thirds or three panels and connected to the kilt hanger using a pair of clasps or clips on each horizontal member. Accordingly, each panel of the folded kilt is connected to a different horizontal member with a center panel of the kilt connected to a central horizontal member and each other panel connected to an outer horizontal member. The outer horizontal members are positioned higher on the arms than the central horizontal member. A vest and jacket can also be placed on the kilt hanger along with a fly plaid that is draped over an optional horizontal dowel member. Methods of using and fabricating the kilt hanger are also disclosed.
