    摘要: A single bias block for a single or multiple low voltage RF circuits including one or more amplifiers and one or more single or double balanced mixers with compensation for temperature and integrated circuit process parameters. The power supply may be a lower voltage without sacrificing the dynamic range of the amplifier and/or mixer by applying full power supply voltage to the load with the bias applied to the base circuit through an operational amplifier and/or buffer circuit. For the mixer, a lower noise figure may also be realized by moving the gain control impedance from the emitter to the collector circuit. The circuits may be discrete components or part of an integrated circuit. Methods are disclosed for reducing the power supply voltage without affecting the dynamic range of an amplifier, for temperature and process parameter compensation, and for controlling the gain of a mixer without affecting input or output impedance.

    摘要: Embodiments of the present invention provide systems, devices and methods for improving both the bandwidth of a BAW resonator bandpass filter and the suppression of out-of-band frequencies above the passband. In various embodiments of the invention, blocker inductors are located in series between the filter input and the filter output to realize both bandwidth enhancement and improved out-of-band frequency rejection. For example, a first blocker inductor may be located at the input and a second blocker inductor may be located at the output of a BAW resonator bandpass filter.

    摘要: A system, apparatus and method for providing filtering functionality and impedance transformation within a BAW resonator network are disclosed. In particular, a BAW resonator network is designed to provide bandpass capability and a transformation between its input impedance and output impedance. By effectively integrating impedance matching functionality within the BAW resonator network, discrete impedance matching elements previously required within a system may be removed or reduced in size. As a result, matching networks and their associated component costs, insertion losses, and board size contributions may be reduced. Harmonic termination may be provided within the BAW resonator network or a prematch stage to improve efficiency of a power amplifier.

    摘要: A monostable circuit responsive conditionally to a circuit input signal for generating a circuit output signal having a pulse of a predetermined duration includes an AND gate having two input ports and an output port. ONe of the input ports is coupled to the circuit input signal and inverts that signal. The other of the input ports is coupled to the circuit output signal. A reset OR gate receives a reset signal and the output of the AND gate. When the reset signal is low, the reset OR gate outputs the output of the AND gate, thus enabling the curcuit. The output of the reset OR gate also goes to a ramp generator having a ramp capacitor, the charging current to which is provided by a current driver. The reference voltage for a comparator is provided by circuitry identical to that associated with the ramp capacitor except that an intermediate bias reference is applied to it. This bias reference is compensated for the effect temperature changes on the circuit. An external current source operating through a current mirror drives the capacitor current driver and the reference voltage. The outputs of the comparator and the reset OR gate are input into the output OR gate for producing the circuit output signal. When the output signal is low, or logic true, the AND gate is latched so that changes in the circuit input signal during this time period do not affect circuit operation.

The timer circuit includes a ramp generator circuit having a first input for receiving an input signal to start a ramp signal, a second input for receiving a ramp timing control signal, and an output for providing a ramp signal. A comparator has a first input coupled to the output of the ramp generator, a second input coupled to a reference voltage source, and an output for providing an end ramp signal. A counter circuit has a first input for receiving the end ramp signal to begin counting, a second input for receiving a counter timing control signal, and an output for providing a terminal count signal. The end ramp signal and the terminal count signal are combined in an AND gate to provide a signal that is delayed by a predetermined amount from the input signal.
