本文报道了一种用于多通道神经记录应用中的电子选址的电池供电遥测命令接收器。接收器通过1-MHz、5-KB/S、幅移键控(ASK)链路，根据4个预定义的选址模式，从总共28个可用选址中选择7个记录选址。然后，可以通过100 MHz调频(FM)链路对选定的七个地点进行无线监控。接收器还执行电源管理以延长电池使用寿命。采用AMI1.5um2P2Mn-well工艺，在一块4.6×4.6 mm的芯片上制作了一个双向无线记录微系统。给出了接收器的设计方法和结构，以及无线模拟前端的测试结果
This paper reports on a battery-powered telemetric command receiver for electronic site selection in multichannel neural recording applications. The receiver selects seven recording sites from a total of 28 available sites, according to four pre-defined site-selection patterns, via a 1-MHz, 5-Kb/s, amplitude-shift-keyed (ASK) link. The seven selected sites can then be wirelessly monitored via a 100-MHz frequency-modulated (FM) link. The receiver also performs power management to increase battery service lifetime. A bidirectional wireless recording microsystem incorporating this receiver is fabricated on a 4.6times4.6-mm2chip using the AMI 1.5mum 2P2M n-well CMOS process. Design methodology and architecture of the receiver together with measurement results from its wireless analog front-end are presented
