A circuit module for a silicon condenser microphone of the present disclosure includes a transducer, a charge pump, an isolator, a first amplifier, a second amplifier, a reaction circuit, a first bias circuit, and a second bias circuit. The charge pump electrically connects to an input port of the transducer, and an output port of the transducer electrically connects to an input port of the first amplifier via the isolator. An output port of the first amplifier electrically connects to an input port of the second amplifier. The reaction circuit is arranged between the output port of the first amplifier and the input port of the transducer. The isolator isolates the direct-current components of the first electrical signal, and therefore, the oscillations of the direct-current components will not affect the performance of the first amplifier.

Disclosed herein a pharmaceutical composition, comprising obovatol as an active ingredient, for the prevention and treatment of neurodegenerative diseases. Having superior inhibitory activity against the production of neurotoxic nitric oxides, the obovatol isolated and purified from Magnoliaceae can be used as active ingredient for a pharmaceutical composition or a neuroprotective agent for the prevention and treatment of neurodegenerative diseases, such as Alzheimer's disease, Parkinson's disease, and multiple sclerosis.
摘要:
An apparatus and system are described for measurement and reporting of Channel State Information (CSI) prediction performance. A user equipment (UE) receives Channel State Information (CSI) Reference Signals (CSI-RS) from a 5th generation NodeB (gNB) at different time instances and performs perform channel measurements on the CSI-RS. The UE calculates a predicted CSI for a later time instance based on the CSI-RS and subsequently performs a channel measurement based on a CSI-RS received in the later time instance. The UE calculates an actual CSI based on the CSI-RS received in the later time instance. determines metrics based on a comparison between the predicted CSI and the actual CSI, and transmits the metrics to the gNB.
