    Abstract: This invention eliminates the need for "capacitor coupling" or "transformer coupling," and the associated undesirable parasitic capacitance and inductance associated with these coupling techniques when designing high frequency (~60GHz) circuits. At this frequency, the distance between two adjacent stages needs to be minimized. A resonant circuit in series with the power or ground leads is used to isolate a biasing signal from a high frequency signal. The introduction of this resonant circuit allows a first stage to be "directly coupled" to a next stage using a metallic trace. The "direct coupling" technique passes both the high frequency signal and the biasing voltage to the next stage. The "direct coupling" approach overcomes the large die area usage when compared to either the "AC coupling" or "transformer coupling" approach since neither capacitors nor transformers are required to transfer the high frequency signals between stages.

    Abstract: Ein Phasenregelkreis (PLL) ist eine wichtige Komponente in drahtlosen Systemen. Die CMOS-Technologie bietet spannungsgesteuerte Oszillatordesigns, die bei 60 GHz arbeiten. Eine der Schwierigkeiten ist die Teilung des Hochfrequenztakts auf eine handhabbare Taktfrequenz unter Verwendung eines herkömmlichen CMOS. Obwohl Injection-Locked-Teiler diese Taktfrequenz teilen können, haben diese Teiler Einschränkungen. Es wird ein Zweiteiler präsentiert, der zur Überwindung dieser Einschränkungen mehrere Techniken verwendet; Vorsteuerung, Taktverstärkung und Reihen-Entzerrspulen.

    Abstract: Abstract A circuit comprises a Sallen-Key filter, which includes a source follower that implements a unity-gain amplifier; and a programmable-gain amplifier coupled to the Sallen-Key filter. The circuit enables programmable gain via adjustment to a current mirror copying ratio in the programmable-gain amplifier, which decouples the bandwidth of the circuit from its gain settings. The programmable-gain amplifier can comprise a differential voltage-to-current converter, a current mirror pair, and programmable output gain stages. The Sallen-Key filter and at least one branch in the programmable-gain amplifier can comprise transistors arranged in identical circuit configurations.

    Abstract: Amplifier (e.g RF or microwave amplifier to drive antenna) comprises an adjustable biasing voltage coupled through a parallel LC load (tank L1) to the output of a first stage (transistor MOSFET N2), which is directly coupled to an input of a second or final (next) stage (transistor MOSFET N3), and whereby at least one characteristic such as quiescent or bias current of second stage N3 is controlled by adjustment of the biasing voltage. This circuit may comprise a reference transistor N1 which is a scaled version of the second or final stage transistor N3. An adjustable current source I4, (or switchable scaled reference transistors of width Wa,Wb,Wc figure 2b) may provide the adjustable reference bias voltage whereby the reference transistor N1 is driven in saturation. The second or final stage transistor may also have a second parallel LC circuit L2 coupling the supply VDD to its output. An input signal Vin on the first stage input (transistor N2) may pass to the output of the first stage 1-6 forming an intermediate signal which is directly coupled to the second stage input (transistor N3). Alternatively a control loop (e.g unity gain operational amplifier) may monitor a biasing voltage to generate an adjustable biasing voltage fed to the parallel LC load L1. Direct coupling, for example with a metallic trace, eliminates the need for capacitor or transformer coupling and undesirable parasitic capacitance/inductance effects in 60GHz microwave circuits, where interstate distances must be minimized. This approach is also economic in terms of IC die area. A method of use is also included.
