1. A 1.5nW 32.768kHz XTAL Oscillator Operational From a 0.3V Supply Notes: 1.1 1.5nW仅在0.3V power下取得,因为功耗和XTAL的幅度紧密相关;而且amplifer使用duty cycling技术,通过计算time of growth and decay of oscillation,在decay of oscillation期间关闭amplifier使得其功耗从2.1nW降低 ...
1. LVL、LVLPUB、ALLPUB和ALL都会保存电源的电流信息。 2. LVL: saving all signal; include node voltage and currents through other components that compute current LVLPUB: saving all signal that are normally useful; exclude signals at internal node on devices Q1:LVL和LVLPUB的差别就是 ...
