Title: 필터제조방법
IPC: B81B1/00
Filed: 2000-04-05
Abstract: 본 발명은 n- 또는 p-도핑된 실리콘 블랭크내에 대체로 일정한 구멍직경을 갖는 미세필터구멍을 에칭하기 위한 전기화학적 에칭방법에 관한 것이다.  상기 블랭크는 양극 또는 음극으로서 전기적으로 연결되고, 에칭전류를 발생시키기 위해 반대전극이 위치되는 에칭액내에 담지되며, 광으로 반사됨으로써, 소수캐리어가 상기 블랭크내에 만들어진다.  소수 캐리어의 발생율은 에칭진행을 증가시킴으로써, 즉 구멍깊이를 증가시킴으로써, 소수 캐리어의 발생율을 감소시키는 방식으로 복사선을 선택함으로써 제어된다.

Title: Amplifier circuit
IPC: H03F3/60
Filed: 2000-05-17
Abstract: An amplifier circuit for amplifying an input signal to generate an amplifier output signal incorporates a cascaded series of reflection amplifiers arranged along a signal path and operative to amplify signals propagating in a forward direction along the signal path. The circuit is operative to counteract signal propagation in a reverse direction along the signal path, thereby hindering spontaneous oscillation from arising within the circuit. Incorporation of reflection amplifiers into the circuit enables it to provide high gain, for example 50 dB, while consuming low currents, for example, tens of microamperes. The circuit is especially suitable for use at intermediate frequencies in radio receivers such as mobile telephones.
