摘要： The duty cycle of a signal is modified by passing the signal through a plurality of inverting stages. The inverting stages each have bias circuitry to influence the input switching threshold of inverters. Multiple duty cycle modification circuits produce non-overlapping local oscillator signals in a system.

摘要： A gain-step transconductor circuit operates with multiple gain values. The gain can be stepped from one gain value to another by selecting a different signal path between an input node and an output amplifier. The output amplifier may operate as a common source amplifier or a common gate amplifier.

摘要： An RF receiver front end includes a variable gain low noise amplifier and/or a variable gain mixer to provide gain variability in the receiver. This gain variability may be used during, for example, automatic gain control operations. In at least one embodiment, the variable gain LNA is a broadband device that is capable of supporting multiple wireless standards.

摘要： A phased-array transmitter and receiver that may be effectively implemented on a silicon substrate. The transmitter distributes to front-ends, and the receiver combines signals from front-ends, using a power distribution/combination tree that employs both passive and active elements. By monitoring the power inputs and outputs, a digital control is able to rapidly provide phase and gain correction information to the front-ends. Such a transmitter/receiver includes a plurality of radio frequency (RF) front-ends and a power splitting/combining network that includes active and passive components configured to distribute signals to/from the front-ends.

摘要： A gate-to-source voltage (Vgs) replication circuit includes a diode-connected NMOS transistor coupled to a current source to draw a drain-to-source current therethrough. The generated Vgs is imposed across a source-to-gate junction of a PMOS transistor. A second PMOS transistor is coupled in series with the first PMOS transistor such that the source-to-gate voltage (Vsg) of the second PMOS transistor replicates the Vgs of the NMOS circuit. The second PMOS transistor is coupled as a source follower to bias other NMOS transistors.
