    Abstract: A low noise amplifier that includes a first cascode, a second cascode, an input circuit, an output node, a first switch, and a second switch. A source of a first common gate transistor and a drain of a first common source transistor of the first cascode are coupled to a first node of the low noise amplifier. The output node is coupled to a drain of the first common gate transistor, and to a drain of a second common gate transistor of the second cascode, thereby coupling the first cascode and the second cascode to a power supply via a load. The first switch is coupled between a gate of the first common gate transistor and the power supply. The second switch is coupled between the first node and the power supply. The first switch is configured to be open and the second switch is configured to be closed when the low noise amplifier operates at a first operational node. The first switch is configured to be closed and the second switch is configured to be open when the low noise amplifier operates at a second operational node that differs from the first operational mode by at least a gain of the low noise amplifier.

    Abstract: A system that may include a first direct current to direct current (DC) converter that is arranged to determine at a first determination rate whether to alter a parameter of operation of the first DC to DC converter and to selectively alter the parameter of operation of operation of the first DC to DC converter in response to the determination; and a second switched-mode DC to DC converter that is arranged to determine at a second determination rate whether to alter the parameter of operation of the second DC to DC converter and to selectively alter the parameter of operation of operation of the second DC to DC converter in response to the determination. The second determination rate is higher by at least a factor of two than the first determination rate. The first and second DC to DC converters are mutually unsynchronized.

    Abstract: Methods and systems are provided for enhanced stereo audio recordings in electronic devices. Stereophonic recording performance in an electronic device, using a first microphone and a second microphone in the electronic device, may be assessed; and processing of signals generated by the first microphone and the second microphone may be configured based on the assessed stereophonic recording performance. The configuring may comprises adaptively modifying the processing to enhance stereophonic recording performance, to match or approximate an ideal performance. The assessing of the stereophonic recording in the electronic device may be based on a type of each of the first microphone and the second microphone, and/or based on a spacing therebetween. The processing may be adaptively modified to simulate directional reception of signals by the first microphone and the second microphone when the microphones are omnidirectional.
