    摘要: A Quarter Size Small Outline Package (QSOP) integrated resistor-capacitor (RC) network includes RC filters with reduced parasitic inductance. In one embodiment, the QSOP integrated RC network includes at least six ground pins (1, 7, 10, 11, 14, 20) for coupling capacitors of the RC filters (2-6, 8, 9, 12, 13, 15-19) with a common ground to maximize the attenuation of ultra-high frequency signals filtered through the RC filters.

    摘要: A thin film protected capacitor structure (300) having a thin film capacitor and a protection device is provided on an integrated circuit wafer. The wafer has a low resistivity substrate (302) of a first type, disposed under an epitaxial layer (304) of a second type different from the first type. The structure includes a first heavily doped region (306), which is of the first type, in and through the epitaxial layer (304), and an oxide layer (308) having a first oxide region disposed above the first heavily doped region (306). The first heavily doped region (306) and the low resistivity substrate (302) form the first plate of the thin film capacitor. There is also included a metal layer (310) disposed above the first oxide region forming the second plate of the thin film capacitor and a second heavily doped region (324) in the epitaxial layer (304).

    摘要: An integrated circuit for implementing a resistor network on a die of the integrated circuit. The integrated circuit includes a common conductor (302), which is disposed on a first side of the die and coupled to resistors (R1...R22) of the resistor network. The integrated circuit further includes a substantially conductive substrate through the die. There is further included a conductive back side contact coupled to the substantially conductive substrate, whereby the common conductor, the substantially substrate, and the conductive back side contact form a common conducting bus from the common conductor to the conductive back side contact through the die.
